عدم المساواة في الدخل في الولايات المتحدة

من ويكيبيديا، الموسوعة الحرة

توزيع الدخل في الولايات المتحدة كان موضوع دراسة من قبل العلماء والمؤسسات. البيانات من عدد من المصادر [1] تشير إلى أن التفاوت في الدخل اتسع بشكل ملحوظ منذ أوائل 1970s ، [2] [3] [4] [5] [6] بعد عدة عقود من الاستقرار . [7] [8] في حين أن عدم المساواة وقد ارتفع بين معظم المتقدمة البلدان، وخاصة تلك الناطقة بالإنجليزية، هو أعلى في الولايات المتحدة. [9] [10] [11]

وتشير الدراسات مصدر اتساع الفجوة (التي تسمى أحيانا الاختلاف الكبير ) لم يكن عدم المساواة بين الجنسين ، والتي انخفضت في الولايات المتحدة على مدى العقود القليلة الماضية، [12] ولا عدم المساواة بين السود والبيض الأميركيين ، والذي ظل راكدا خلال تلك الفترة ، [13] كما لم الفجوة بين الفقراء والطبقة المتوسطة كانت سببا رئيسيا على الرغم نمت عليه. [14] وكان معظم النمو بين الطبقة الوسطى والأعلى دخلا، مع التفاوت تصبح أكثر تطرفا كذلك واحدة ترتفع في توزيع الدخل. [15]

الأولى 2011 دراسة من قبل البنك المركزي العماني [16] وجدت أن أفضل كسب 1 في المائة من الأسر اكتسبت حوالي 275٪ بعد خصم الضرائب الاتحادية وتحويلات الدخل على مدى فترة بين عامي 1979 و 2007، مقارنة مع زيادة قدرها 40٪ فقط تحت ل60 في المئة في وسط توزيع الدخل في أميركا. [16] إيجاد مصادر أخرى أن الاتجاه قد استمر منذ ذلك الحين. [17] ومع ذلك، 42٪ فقط من الأمريكيين يعتقدون زاد عدم المساواة في السنوات العشر الماضية. [18] عدم المساواة في الدخل ليست موحدة بين الدول؛ مقاسا معامل جيني : بعد أن كان التفاوت في الدخل الضريبي في عام 2009 في ولاية تكساس أكبر وأقل في ولاية ماين . [19]

العلماء وغيرهم تختلف عن أسباب، والحلول، وأهمية هذا الاتجاه، [20] [21] في عام 2011 مما ساعد على إشعال "احتلوا" حركة الاحتجاج . وكثيرا ما يستشهد التعليم وزيادة الطلب على العمالة الماهرة كأسباب، [22] وقد أكد البعض أهمية السياسة العامة؛ يعتقد البعض الآخر السبب (ق) من ارتفاع عدم المساواة في غير مفهومة جيدا. [16] وقد وصفت عدم المساواة على حد سواء لا صلة له في مواجهة الفرص الاقتصادية (أو الحراك الاجتماعي ) في أمريكا، وكسبب للتراجع في تلك الفرصة. [23] [24]

تاريخ

التفاوت الولايات المتحدة من 1913-2008 [25] .

حصة دخل الأسرة قبل خصم الضرائب التي وردت إلى أعلى 1 في المئة، وأعلى بنسبة 0.1 في المئة وأعلى بنسبة 0.01 في المئة بين عامي 1917 و 2005. [26] [27]

لم يكن مستوى تركيز الدخل في أمريكا ثابتة طوال تاريخها. تعود إلى أوائل القرن 20th، عندما بدأت إحصاءات الدخل لتصبح متاحة، كان هناك "قوس اقتصادية كبيرة" من ​​عدم المساواة العالية "في المساواة النسبية والعودة مرة أخرى"، على حد تعبير الخبير الاقتصادي الحائز على جائزة نوبل بول كروغمان . [28] في عام 1915، وهي الحقبة التي روكفلر و Carnegies تهيمن الصناعة الأميركية، وحصل أغنى 1٪ من الأميركيين تقريبا 18٪ من كل الدخل. بحلول عام 2007، وأعلى 1 في المئة لحساب 24٪ من مجموع الدخل. [29] في بين، تراجعت حصتها إلى أقل من 10٪ على مدى ثلاثة عقود.

في الحقبة الأولى من التفاوت استمرت ما يقرب من حقبة ما بعد الحرب الأهلية ("في العصر الذهبي ") لوقت ما حوالي 1937. ولكن من حوالي 1937-1947، وهي الفترة التي تم ويطلق عليها اسم " ضغط كبير " [30] انخفض التفاوت في الدخل في أمريكا بشكل كبير. التدريجي للغاية الصفقة الجديدة الضريبية، وتعزيز نقابات، وتنظيم مجلس الحرب العمالة الوطنية خلال الحرب العالمية الثانية رفع دخل الفقراء والطبقة العاملة وخفضت من أن كبار أصحاب الدخول. [31] وهذا "المجتمع الطبقة المتوسطة" من ​​نسبيا وظل انخفاض مستوى التفاوت ثابت إلى حد كبير لحوالي ثلاثة عقود تنتهي في أوائل 1970s، [7] [30] [32] نتاج الأجور المرتفعة نسبيا للولايات المتحدة على الطبقة العاملة والدعم السياسي لتسوية السياسات الحكومية الدخل.

ظلت الأجور المرتفعة نسبيا بسبب عدم وجود منافسة أجنبية لتصنيع الأمريكية، والافتقار إلى انخفاض العمال المهاجرين المهرة، [33] المنافسة للعمال الولايات المتحدة في العام، و- ربما أكثرها أهمية - النقابات قوية. بحلول عام 1947 أكثر من ثلث العمال غير الزراعية وأعضاء النقابة، [34] والنقابات أثار كل من متوسط ​​الأجور لأعضائها، وبشكل غير مباشر وإلى حد أقل، رفعت الأجور للعاملين في المهن المماثلة غير ممثلة من قبل النقابات. [35 ] العلماء يعتقدون وقدمت الدعم السياسي لمعادلة السياسات الحكومية إقبالا كبيرا من الناخبين من التصويت محركات الاتحاد، بدعم من المحافظ إلا الجنوبية للصفقة الجديدة، والهيبة التي حشد هائل وانتصار الحرب العالمية الثانية أعطت الحكومة. [ 36]

عودة إلى الأعلى عدم المساواة أو ما كروغمان والصحفي تيموثي نوح وقد أشار باسم " الاختلاف الكبير " [29] ، وبدأ في 1970s.

وفوائد زيادة الإنتاجية على مدى السنوات ال 35 الماضية لم يذهب إلى الطبقة الوسطى [37]

وقد وجدت الدراسات نما الدخل أكثر تفاوتا بشكل مستمر تقريبا ما عدا خلال فترات الركود الاقتصادي في 1990-1991 و 2001 ( فقاعة دوت كوم )، و تمثال نصفي 2007 الرهن العقاري الثانوي . [38] [39]

والاختلاف الكبير يختلف في بعض النواحي من عصر ما قبل الكساد عدم المساواة. قبل عام 1937 حصة أكبر من الدخل أعلى الأجراء جاء من رأس المال (الفائدة وأرباح الأسهم، والدخل من الإيجار، ومكاسب رأس المال). آخر عام 1970، دخل دافعي الضرائب ذات الدخل المرتفع يأتي في الغالب من "العمل"، أي تعويض العمل. [40]

حتى عام 2011، كان الاختلاف العظيم لم يكن قضية سياسية كبرى في أمريكا، على الرغم من ركود الدخل والطبقة المتوسطة. في عام 2009 باراك أوباما إدارة البيت الأبيض فرقة أسر الطبقة العاملة الأوسط عقدت في التركيز على القضايا الاقتصادية التي تؤثر بشكل خاص الأمريكيين المتوسطة الدخل. في عام 2011، و حركة احتلوا وجه اهتماما كبيرا لعدم المساواة في الدخل في البلاد.

معظم الإحصاءات الأخيرة

من 1992-2007 شهد أعلى 400 الأجراء في الولايات المتحدة زيادة دخلها 392٪ ومتوسط ​​معدل الضريبة على تخفيض بنسبة 37٪. [41] حصة من إجمالي الدخل في أمريكا ذاهب الى أعلى 1٪ من الأسر الأميركية (أيضا بعد الاتحادية زيادة الضرائب وتحويلات الدخل) من 11.3٪ في عام 1979 إلى 20.9٪ في عام 2007. [42] وخلال الكساد الكبير 2007-2009، انخفض التفاوت، مع إجمالي الدخل يذهب إلى أسفل 99 في المئة من الأميركيين تراجع بنسبة 11.6٪، ولكن السقوط أسرع (36.3٪) لأعلى 1٪. [43] [44] ومع ذلك التفاوت في الدخل زيادة مرة أخرى خلال الانتعاش 2009-2010، مع أعلى 1٪ من ذوي الدخل التقاط 11.6٪ من الدخل وأرباح رأس المال، والدخل من جهة أخرى 99٪ ظلت مستقرة، نموا بنسبة 0.2٪ فقط. [45] [46]

التضخم المعدل زيادة في الدخل بعد خصم الضرائب المنزلية بين عامي 1979 و 2005 لأعلى 1٪ وأربعة الأخماس الخمسة. [47]

ويبين هذا الرسم البياني دخل المئوية نظرا 1947-2010 دولار في عام 2010. الأعمدة 2 من الأرقام في الهامش الأيمن 1970-2010 هي النمو التراكمي ومعدل النمو السنوي خلال تلك الفترة. المقياس العمودي لوغاريتمي، الأمر الذي يجعل نسبة النمو المستمر تبدو وكأنها خط مستقيم. من 1947-1970، ارتفعت جميع المئوية في جوهرها نفس المعدل؛ ضوء، وخطوط مستقيمة والنسب المئوية لمختلفة لتلك السنوات جميعها نفس المنحدر. منذ ذلك الحين، لم يكن هناك اختلاف كبير، مع المئوية مختلفة من توزيع الدخل تنمو بمعدلات مختلفة. لعائلة أمريكية وسيطة، هذه الفجوة هو 39000 $ سنويا (أكثر من 100 دولار في اليوم الواحد): إذا كان النمو الاقتصادي خلال هذه الفترة قد تم تقاسمها على نطاق واسع كما كان 1947-1970، فإن متوسط ​​دخل الأسرة كانت 39000 $ سنويا أعلى مما كان عليه في عام 2010. تم إنشاء هذه المؤامرة من خلال الجمع بين بيانات من مكتب الإحصاء الأميركي [48] ودائرة الإيرادات الداخلية في الولايات المتحدة. [49] وهناك اختلافات منهجية بين هذين المصدرين، ولكن الاختلافات هي صغيرة بالنسبة لحجم هذه المؤامرة. [50]

وهناك عدد من الدراسات من قبل الولايات المتحدة وزارة التجارة ، مكتب الميزانية في الكونغرس (البنك المركزي العماني)، و دائرة الإيرادات الداخلية ، وقد وجدت أن توزيع الدخل في الولايات المتحدة - قياس الأكثر شيوعا من قبل الأسرة أو الفرد - أصبحت غير متكافئة على نحو متزايد منذ 1970s .

كان واحدا من أحدث الدراسات وشامل عن تغير في عدم المساواة في الدخل في أمريكا عام 2011 دراسة قام بها مكتب الميزانية في الكونغرس (البنك المركزي العماني) - "اتجاهات في توزيع دخل الأسرة بين عامي 1979 و 2007". (واختار هذين العامين على حد سواء لأنها سبقت الركود الاقتصادي وكذلك كانت كلتا الفترتين من "النشاط الاقتصادي مماثلة العام" [51] ). وجد التقرير أن دخل الأسرة الحقيقي بعد خصم الضرائب الاتحادية وبما في ذلك التحويلات الحكومية (المدفوعات من الضمان الاجتماعي ، والتأمين ضد البطالة ، الخ [52] [53] ) بنسبة 62٪.

ومع ذلك، نما الدخل من الأسر في أعلى 1 بالمائة من أصحاب بواسطة 275٪، مقارنة ب 65٪ لل19 بالمئة في العام المقبل، فقط تحت 40٪ لل60 بالمئة في العام المقبل، و 18٪ لأسفل الخامس من الأسر. "ونتيجة لهذا النمو غير المتكافئ للدخل"، وأشار التقرير، "حصة من إجمالي الدخل بعد خصم الضرائب التي وردت إلى 1 في المئة من السكان في الأسر التي لديها أعلى دخل أكثر من الضعف بين عامي 1979 و 2007، في حين تلقت حصة ورفض من قبل الأسر المنخفضة الدخل والمتوسطة الدخل ... نمت حصة الدخل التي تلقتها أعلى 1 في المئة من نحو 8٪ في عام 1979 إلى أكثر من 17٪ في عام 2007. حصة تلقتها 19 في المئة أخرى من الأسر في أعلى دخل الخمس كان (خمس من السكان كما مقسوما الدخل) شقة إلى حد ما خلال الفترة نفسها، مرتفعا من 35٪ إلى 36٪ ". [54]

البنك المركزي العماني وفقا ل، [55] وكان السبب الرئيسي لارتفاع الملحوظ في التوزيع غير المتساوي للدخل بعد خصم الضرائب زيادة في الدخل السوق، وهذا هو دخل الأسرة قبل الضرائب والتحويلات. دخل السوق لمنزل هو مزيج من دخل العمل (مثل الأجور النقدية والمزايا المدفوعة رب العمل، رب العمل أجرا الضرائب المفروضة على الرواتب)، الإيرادات التجارية (مثل الدخل من الشركات والمزارع تعمل فقط من قبل أصحابها)، مكاسب رأس المال (الأرباح تتحقق من بيع الأصول، وخيارات الأسهم)، دخل رأس المال (مثل الفوائد من الودائع وأرباح الأسهم وإيرادات الإيجار)، والإيرادات الأخرى. من هذه، وشكلت أرباح رأس المال عن 80٪ من الزيادة في الدخل السوق للأسر في أعلى 20٪، في الفترة 2000-2007. حتى على الفترة 1991-2000، وفقا للبنك المركزي العماني، وشكلت أرباح رأس المال لمدة 45٪ من الدخل السوق لأعلى الأسر 20٪.

الرواد في مجال استخدام بيانات الدخل IRS لتحليل توزيع الدخل هي إيمانويل سايز و توماس Piketty في كلية باريس للاقتصاد أظهرت أن حصة الدخل التي عقدها أعلى 1 في المئة كما كان كبير في عام 2005 كما في عام 1928. [5] مصادر أخرى وقد لاحظ أن زيادة التفاوت الاقتصادي وشملت جانيت يلين الذي قال، "تركزت النمو [في الدخل الحقيقي] بشكل كبير جدا في الطرف من أعلى، وهذا هو، وأعلى 1 في المئة". [56]

وقد لخص الخبير الاقتصادي تيموثي Smeeding تصل الاتجاه الحالي: [57]

الامريكيين لديهم أعلى التفاوت في الدخل في العالم الغني وعلى مدى السنوات الماضية شهدت 20-30 الأميركيين أيضا أكبر زيادة في التفاوت في الدخل بين الدول الغنية. وأكثر تفصيلا البيانات التي يمكن استخدامها لمراقبة هذا التغيير، والمزيد من الانحراف التغيير يبدو أن ... غالبية المكاسب الكبيرة هي في الواقع في الجزء العلوي من التوزيع.

الولايات المتحدة الأمريكية تعداد الدراسات المكتب عن عدم المساواة في الدخل على حد سواء الأسر التدبير [58] والأفراد. [59] أعدادهم تظهر مستويات أقل من عدم المساواة [60] ولكنها لا تشمل بيانات عن الأسر ذات الدخل الأعلى، حيث ان معظم التغير في توزيع الدخل لديها حدث. [20] [61] [62] [63]

Comparisons of income over time should adjust for changes in average age, family size, number of breadwinners, and other characteristics of a population. Measuring personal income ignores dependent children, but household income also has problems—a household of ten has a lower standard of living than one of two people, though the income of the two households may be the same. [65]

People's earnings tend to rise over their working lifetimes, so “snapshot measures of income inequality can be misleading.” [66] The inequality of a recent college graduate and a 55-year-old at the peak of his/her career is not an issue if the graduate has the same career path.

Conservative researchers and organizations have focused on the flaws of household income as a measure for standard of living in order to refute claims that income inequality is growing, becoming excessive or posing a problem for society. [67] According to sociologist Dennis Gilbert, growing inequality can be explained in part by growing participation of women in the workforce. High earning households are more likely to be dual earner households, [7] And according to a 2004 analysis of income quintile data by the Heritage Foundation , inequality becomes less when household income is adjusted for size of household. Aggregate share of income held by the upper quintile (the top earning 20 percent) decreases by 20.3% when figures are adjusted to reflect household size. [68]

However the Pew Research Center found household income has appeared to decline less than individual income in the twenty-first century because those who are no longer able to afford their own housing have increasingly been moving in with relatives, creating larger households with more income earners in them. [69]

The 2011 CBO study “Trends in the Distribution of Household Income” mentioned in this article adjusts for household size so that its quintiles contain an equal number of people, not an equal number of households. [70]

Looking at the issue of how frequently workers or households move into higher or lower quintiles as their income rises or falls over the years, [71] the CBO found income distribution over a multi-year period “modestly” more equal than annual income. [72] The CBO study confirms earlier studies. [47]

Overall, according to Timothy Noah, correcting for demographic factors (today's population is older than it was 33 years ago, and divorce and single parenthood have made households smaller), you find that income inequality, though less extreme than shown by the standard measure, is also growing faster than shown by the standard measure. [73]

Wage inequality

According to Janet L. Yellen, President and CEO, Federal Reserve Bank of San Francisco,

…real hourly wages of those in the 90th percentile—where most people have college or advanced degrees—rose by 30% or more… among this top 10 percent, the growth was heavily concentrated at the very tip of the top, that is, the top 1 percent. This includes the people who earn the very highest salaries in the US economy, like sports and entertainment stars, investment bankers and venture capitalists, corporate attorneys, and CEOs. In contrast, at the 50th percentile and below—where many people have at most a high school diploma—real wages rose by only 5 to 10% – [56]

Lisa Shalett of Merrill Lynch Wealth Management, found that,real average hourly earnings in the US “are essentially flat to down, with today's inflation-adjusted wage equating to about the same level as that attained by workers in 1970″, despite the fact that “for the last two decades and especially in the current period”, productivity has “soared”. The benefits of productivity during this cycle had gone “almost exclusively to corporations and their very top executives.” [74]

Gini index

Further information: Gini coefficient

The Gini coefficient summarizes income inequality in a single number and is one of the most commonly used measures of income inequality. It uses a scale from 0 to 1 — the higher the number the more inequality. 0 represents perfect equality (everyone having exactly the same income), and 1 represents perfect inequality (one person having all income). (Index scores are commonly multiplied by 100 to make them easier to understand. [75] ) Gini index ratings can be used to compare inequality within (by race, gender, employment) and between countries, before and after taxes. [76] [77] [78] [79] Different sources will often give different gini values for the same country or population measured.

Comparisons by state

This Gini Index map shows regional and county level variation in pre-tax income inequality Gini index. The 2010 Gini index value range from 0.207 for Loving County ( Texas ) to 0.645 to East Carroll Parish ( Louisiana ). [80]

The household income Gini index for the United States was 0.468 in 2009, according to the US Census Bureau , [81] though it varied significantly between states . The states of Utah, Alaska and Wyoming have a pre-tax income inequality Gini coefficient that is 10% lower than the average, while Washington DC and Puerto Rico 10% higher. After including the effects of federal and state taxes, the US Federal Reserve estimates 34 states in the USA have a Gini coefficient between 0.30 and 0.35, with the state of Maine the lowest. [19] At the county and municipality levels, the pre-tax Gini index ranged from 0.21 to 0.65 in 2010 across the United States, according to Census Bureau estimates. [80]

OECD estimates the pre-tax Gini index for the United States was 0.49, and after-tax Gini index was 0.38, in 2008-2009. The average pre-tax Gini index for OECD countries was 0.46, while the average after-tax Gini index was 0.31. [76]

International comparisons

The UN , CIA World Factbook , [82] and OECD have used the gini index to compare inequality between countries, and as of 2006, the United States had one of the highest levels of income inequality among similar developed or high income countries , as measured by the index. [9] While inequality has increased since 1981 in two-thirds of OECD countries [12] [83] most developed countries are in the lower, more equal, end of the spectrum, with a Gini coefficient in the high twenties to mid thirties. [84]

The gini rating of the United States is sufficiently high, however, to put it among less developed countries. The US ranks above (more unequal than) South American countries such Guyana, Nicaragua, and Venezuela, and roughly on par with Uruguay, Nicaragua, and Venezuela, according to the CIA. [85] (although some developed countries have higher gini ratings before taxes and transfers. [10] )

Between 1985 and 2008 the OECD-24 countries with the fastest-rising Gini coefficients were Sweden, New Zealand, Finland, Israel, Germany, and Luxembourg. [86]

Among the 34 “developed” countries of the OECD the US gini rank in income equality (27th) is higher before taxes and “transfers” are measured, [90] then after (31st) [91] —ie, the US has less income redistribution by government than some other post-industrial economies. However some developed countries, such as the Netherlands and Greece, have less inequality simply because incomes are more equal than in the US even before taxes. [92]

Some have argued that inequality is higher in other countries than official statistics indicate because of unreported income. European countries have higher amounts of wealth in offshore holdings. [93] [94] [95] [96]

Income levels

High income

60% of earners in the top 0.1 percent are executives, managers, supervisors, and financial professionals. More than half of them work in closely held businesses. [97] The top 1 percent is composed of many professions, the five most common professions being managers , [98] physicians , administrators , lawyers , and financial specialists. Doctors are more likely than any other profession to be in the 1 percent. [99]

Causes

Inequality in general

Expertise, productiveness and work experience, inheritance, gender, and race have had a strong influence on distribution of personal income [100] [101] in the United States as in other countries.

Race and gender disparities

Income levels vary by gender and race with median income levels considerably below the national median for females compared to men with certain racial demographics. [102]

Median personal income by gender and race in 2005.

Despite considerable progress in pursuing gender and racial equality, some social scientists attribute these discrepancies in income to continued discrimination. [103] Others argue that the majority of the wage gap is due to women's choices and preferences. Women are more likely to consider factors other than salary when looking for employment. On average, women are less willing to travel or relocate, take more hours off and work fewer hours, and choose college majors that lead to lower paying jobs. Women are also more likely to work for governments or non-profits, that pay less than the private sector. [104] [105] According to this perspective certain ethnic minorities and women receive fewer promotions and opportunities for occupation and economic advancement than others. In the case of women this concept is referred to as the glass ceiling keeping women from climbing the occupational ladder.

In terms of race, Asian Americans are far more likely to be in the highest earning 5 percent than the rest of Americans. [106]

However studies have shown that African Americans are less likely to be hired than European-Americans with the same qualifications. [107] The continued prevalence of traditional gender roles and ethnic stereotypes may partially account for current levels of discrimination. [103] In 2005, median income levels were highest among Asian and White males and lowest among females of all races, especially those identifying as African American or Hispanic. Despite closing gender and racial gaps, considerable discrepancies remain among racial and gender demographics, even at the same level of educational attainment. [108] The success of Asian Americans may come from how parents and children spend much longer hours on education than their peers. Asian American have significantly higher college graduation rates than their peers and are much more likely to enter high status occupations. [109]

Median weekly earnings of full-time wage and salary workers, by sex, race, and ethnicity, 2009. [110]

Since 1953 the income gap between male and female workers has decreased considerably but remains relatively large. [111] Women currently earn significantly more Associate's, Bachelor's, and Master's degrees than men and almost as many Doctorates. [112] Women are projected to have passed men in Doctorates earned in 2006–2007, and to earn nearly two thirds of Associate's, Bachelor's, and Master's degrees by 2016. [113] Despite this, some [ who? ] still argue that male workers still hold higher educational attainment, as the success of women in academia is a relatively new phenomenon. [100]

Though it is important to note that income inequality between sexes remained stark at all levels of educational attainment. [102] Between 1953 and 2005 median earnings as well as educational attainment increased, at a far greater pace for women than for men. Median income for female earners male earners increased 157.2% versus 36.2% for men, over four times as fast. Today the median male worker earns roughly 68.36% more than their female counterparts, compared to 176.25% in 1953. The median income of men in 2005 was 2% higher than in 1973 compared to a 74.6% increase for female earners. [111]

Racial differences remained stark as well, with the highest earning sex-gender demographic of workers aged 25 or older, Asian males (who were roughly tied with white males ) earning slightly more than twice as much as the lowest-earning demographic, Hispanic females. [114] [115] As mentioned above, inequality between races and gender persisted at similar education levels. [115] [116] Racial differences were overall more pronounced among male than among female income earners. In 2009, Hispanics were more than twice as likely to be poor than non-Hispanic whites, research indicates. [117] Lower average English ability, low levels of educational attainment, part-time employment, the youthfulness of Hispanic household heads, and the 2007–09 recession are important factors that have pushed up the Hispanic poverty rate relative to non-Hispanic whites.

During the early 1920s, median earnings decreased for both sexes, not increasing substantially until the late 1990s. Since 1974 the median income for workers of both sexes increased by 31.7% from $18,474 to $24,325, reaching its high-point in 2000. [118]

Education and technology

Median personal and household income according to different education levels. [131] [133]

Income differences between the varying levels of educational attainment (usually measured by the highest degree of education an individual has completed) have increased. Expertise and skill certified through an academic degree translates into increased scarcity of an individual's occupational qualification which in turn leads to greater economic rewards. [134] As the United States has developed into a post-industrial society more and more employers require expertise that they did not a generation ago, while the manufacturing sector which employed many of those lacking a post-secondary education is decreasing in size. [135]

In the resulting economic job market the income discrepancy between the working class and the professional with the higher academic degrees, [100] who possess scarce amounts of certified expertise, may be growing.

Households in the upper quintiles are generally home to more, better educated and employed working income earners, than those in lower quintiles. [68] Among those in the upper quintile, 62% of householders were college graduates, 80% worked full-time and 76% of households had two or more income earners, compared to the national percentages of 27%, 58% and 42%, respectively. [100] [101] [136] Upper-most sphere US Census Bureau data indicated that occupational achievement and the possession of scarce skills correlates with higher income. [136]

Average earnings in 2002 for the population 18 years and over were higher at each progressively higher level of education… This relationship holds true not only for the entire population but also across most subgroups. Within each specific educational level, earnings differed by sex and race. This variation may result from a variety of factors, such as occupation, working full- or part-time, age, or labor force experience. – [100] [137]

Percent of households with 2+ income earners, and full-time workers by income. [136]

In the context of concern over income inequality a number of economists, such as Federal Reserve chairman Ben Bernake, have talked about the importance of incentives: “… without the possibility of unequal outcomes tied to differences in effort and skill, the economic incentive for productive behavior would be eliminated, and our market-based economy … would function far less effectively.” [134] [138] Yale economist Arthur Okun argues there is a trade-off between economic growth and economic redistribution. [139] [140]

Since abundant supply decreases market value, the possession of scarce skills considerably increases income. [100] Among the American lower class , the most common source of income was not occupation, but government welfare. [141]

فرض الضرائب

Average tax rate percentages for the highest-income US taxpayers, 1945-2009

Another factor in income inequality/equality is the effective rate at which income is taxed coupled with the progressivity of the tax system. A progressive tax is a tax by which the tax rate increases as the taxable base amount increases. [142] [143] [144] [145] [146] Overall income tax rates in the United States are below the OECD average, and until 2005 have been declining. [147]

Post-1980 rise in inequality

Most current discussion of income inequality in America centers on its rise since the mind to late 1970s, the so-called “ Great Divergence “. According to the United States Census Bureau , it reported that the income inequality between the richest and poorest people grew to its widest in 2011, as the census recorded 46.2 million people living in poverty . [148]

Broad breakdown

Breaking down how much of the increase in income inequality between 1979 and 2007 came from distribution of pre-tax income and how much from taxes and “government transfers”, the CBO data shows that the 33% increase in inequality [149] came from a

  • 23% increase in inequality from changes in distribution of “market income” to households (top earners received a larger share of salaries, interest, dividends, capital gains, business income, etc.); a
  • 6% increase from changes in “government transfers” (social security, unemployment, the end of AFDC welfare, etc.); and a
  • 4% increase from changes in federal taxation (overall decline in the average federal tax rate and shift in federal revenues from income taxes to less progressive payroll taxes, etc.).

[150] [151]

Of the 23% increase in inequality from changes in pre-tax “market” income, most of that (79%) came from a shift to top earners in different types of income across the board. A smaller amount of inequality increase (21%) came from a shift from wages and salaries to more concentrated income sources—ie interest, dividends, business income and especially capital gains, which are more concentrated toward top earners than income from salaries/wages. [152]

According to Michael Cembalest, the chief investment officer of JPMorgan Chase , [153] as of 2011, corporate “profit margins have reached levels not seen in decades,” and “reductions in wages and benefits explain the majority of the net improvement. … US labor compensation is now at a 50-year low relative to both company sales and US GDP” [154]

Lisa Shalett, chief investment officer at Merrill Lynch Wealth Management noted that, “for the last two decades and especially in the current period, … productivity soared … [but] US real average hourly earnings are essentially flat to down, with today's inflation-adjusted wage equating to about the same level as that attained by workers in 1970. … So where have the benefits of technology-driven productivity cycle gone? Almost exclusively to corporations and their very top executives.” [74]

Explanations

وفقا لمكتب الموازنة في الكونغرس وغيرها، "الأسباب الدقيقة ل[الأخيرة] النمو السريع في الدخل في أعلى ليست مفهومة جيدا"، [40] [85] ولكن "في جميع الاحتمالات"، وهو "تفاعل عوامل متعددة" كان . المعنية [155] ". وعرضت الباحثون عدة مبررات محتملة" [40] [56] . بعض هذه المبررات الصراع، وبعض التداخل [156] وهي تشمل:

  • تم عولمة فرضية منخفضة العمال المهرة الأمريكية يتراجع في وجه المنافسة من العمال من ذوي الأجور المتدنية في آسيا واقتصادات أخرى "الناشئة"؛ [157]
  • المنحازة مهارة التغير التكنولوجي - تسارع وتيرة التقدم في مجال تكنولوجيا المعلومات وزيادة الطلب على ذوي المهارات العالية والمتعلمين ذلك يفضل أن توزيع الدخل العقول بدلا من العضلات؛ [157]
  • التكنولوجيات الحديثة فرضية النجم الاتصالات غالبا ما تتحول المنافسة في البطولة التي يكافأ الفائز غنية، في حين أن الوصيف على أقل بكثير مما كانت عليه في الماضي؛ [157] [158]
  • هجرة العمال الأقل تعليما - مستويات عالية نسبيا من هجرة العمال ذوي المهارات المنخفضة منذ عام 1965 قد خفضت الأجور لالمتسربين من المدارس الثانوية الأميركية المولد؛ [159]
  • السياسة والسياسة - ارتفاع التعويضات التنفيذية ، وركود الأجور المتوسطة الدخل والضرائب أكثر رجعية الناتجة عن القرارات السياسية، وليس قوى السوق. قرار مثل عدم التدخل لوقف القبض التنفيذي لمجالس إدارات الشركات، وسحق النقابات العمالية، الخ

تحليل أكبر ثلاث فرضيات، الخبير الاقتصادي بول كروغمان جدت لها أن تكون "غير كافية على نحو متزايد"، كما مزيد من الأدلة المتراكمة.

يمكن أن العولمة شرح جزء من الانخفاض النسبي في الأجور من ذوي الياقات الزرقاء، لكنه لا يمكن أن يفسر ارتفاع 2،500 في المئة في الدخل الرئيس التنفيذي. التكنولوجيا قد يفسر لماذا ارتفع قسط الراتب المرتبطة التعليم الجامعي، ولكن من الصعب أن تتطابق مع الزيادة الهائلة في التفاوت بين، دون إحراز تقدم يذكر على تعليم جامعي للعديد من المكاسب ولكن العملاق في الأعلى. نظرية نجم يعمل ل جاي لينو ، ولكن ليس للآلاف من الناس الذين أصبحوا أغنياء بذهول دون المرور على شاشة التلفزيون. [157]

الهجرة وأيضا وجدت الرغبة كتفسير. [160]

غيره من العلماء [161] التشكيك في التفسير من التحصيل العلمي والمهارات في مكان العمل تشير إلى أن البلدان الأخرى ذات مستويات التعليم والاقتصادات مماثلة لم تسر السبيل للولايات المتحدة، والتي لم يتبع تركيز الدخل في الولايات المتحدة وجود نمط من " 29٪ من الأمريكيين مع شهادات جامعية تبتعد "من أولئك الذين لديهم تعليم أقل. [57] [162] [163] [164] [165] [9]

التغير التكنولوجي المنحازة المهارة

اعتبارا من منتصف إلى أواخر عقود من 2000s، وكان التفسير الأكثر شيوعا لعدم المساواة في الدخل في أمريكا "التغيير منحازة المهارة التكنولوجية" [166] - "تحولا في تكنولوجيا الإنتاج التي تفضل المهرة غير المهرة على العمل من خلال زيادة لها النسبية الإنتاجية ، وبالتالي النسبي الطلب ". [167] على سبيل المثال، يقدر ندوة علمية حول موضوع واحد التي شملت العديد من الاقتصاديين البارزين العمل أن التغير التكنولوجي كانت مسؤولة عن أكثر من 40٪ من الزيادة في عدم المساواة. عوامل أخرى مثل التجارة الدولية، وانخفاض في الحد الأدنى للأجور الحقيقية، وانخفاض في النقابات وارتفاع الهجرة، كانت كل منها مسؤولة عن 10-15٪ من هذه الزيادة. [168] [169]

تظهر الأرقام مدى قوة تأثير التعليم على توزيع الدخل. [170] وفي عام 2005، ما يقرب من 55٪ من ذوي الدخل مع درجة الدكتوراه - كانوا من بين 15 في المائة الأعلى دخلا - الأكثر تعليما 1.4٪. بين أولئك الذين لديهم درجة الماجستير - الأكثر تعليما 10٪ - وكان ما يقرب من نصف الدخل بين أعلى 20 في المئة من الأجراء. [131] فقط بين الأسر في الخمس الأعلى والأسر مع شهادات جامعية في الأغلبية. [101]

ولكن في حين أن التعليم العالي يترجم عادة إلى الدخل العالي، [170] والمتعلمين يتم تمثيل غير متناسب في الأسر الخمس العليا ، تفشل الاختلافات في التحصيل العلمي لشرح التباين في الدخل بين أعلى 1 في المئة والباقي من السكان. نسب كبيرة من الأفراد تفتقر إلى شهادة جامعية موجودة في جميع العوامل الديموغرافية الدخل، بما في ذلك 33٪ من المصابين المعيلات مع ستة الرقم الدخل . [101] من 2000 إلى 2010، وبنسبة 1.5٪ من الأمريكيين مع MD، دينار، أو ماجستير في إدارة الأعمال و 1.5٪ تحمل شهادة دكتوراه شهدت مكاسب دخل وسيطة من حوالي 5٪. بين أولئك الذين لديهم كلية أو درجة الماجستير (حوالي 25٪ من القوى العاملة الأمريكية) انخفض متوسط ​​الأجور بنسبة حوالي 7٪، (رغم أن هذا كان أقل من الانخفاض في الأجور لأولئك الذين لم تستكمل الكلية). [171]

تقترب القضية من المهن التي تم استبدالها أو تقليله منذ أواخر 1970s، وجدت أحد الباحثين أن الوظائف التي "تتطلب بعض التفكير ولكن ليس الكثير" - أو المهن من الطبقة المتوسطة المهرة معتدلة مثل الصرافين، الطابعين، لحام، والمزارعين، والأجهزة انخفض أبعد في معدلات الأجور و / أو أرقام - مصلحي. فرص العمل التي تتطلب مهارة أو أكثر إما كان أقل أقل تأثرا. [172] إلا أن توقيت التغيير التكنولوجي الهائل في استخدام الانترنت من قبل عصر الأعمال ابتداء من أواخر 1990s-لا يتطابق مع نمو عدم المساواة في الدخل (بدءا من عام 1970s في وقت مبكر ولكن إلى حد ما تباطؤ في 1990s). فضلا عن ذلك فإن إدخال التكنولوجيات التي تزيد من الطلب على العمال المهرة أكثر ويبدو أن تترافق عموما مع اختلاف في دخل الأسرة بين السكان. الاختراعات في القرن 20 مثل الطاقة الكهربائية AC ، والسيارات، والطائرات، والإذاعة والتلفزيون والغسالة، وآلة زيروكس، كان كل أثر الاقتصادية على قدم المساواة من أجهزة الكمبيوتر / المعالجات / الانترنت ولكن لم يتزامن مع زيادة عدم المساواة. [172 ]

تعليم

تفسير آخر هو أن الجمع بين إدخال التكنولوجيات التي تزيد من الطلب على العمال المهرة، وفشل نظام التعليم الأميركي لتوفير زيادة كافية في تلك العمال المهرة ومزايدة على رواتب هؤلاء العمال ". مثال على التباطؤ في نمو التعليم في أمريكا (التي بدأت حول نفس الوقت الذي بدأ الاختلاف الكبير) هو حقيقة أن الشخص العادي ولدت في عام 1945 تلقى أكثر من عامين من الدراسة والديه، في حين أن الشخص العادي ولدت في عام 1975 لم تتلق سوى عام ونصف العام أكثر من التعليم. [173] تقدير الكاتب تيموثي نوح "العودة من المغلف" على أساس "مركب من مناقشاتي مع والقراءة من مختلف الاقتصاديين وعلماء السياسة" أن "الفشل مختلف" في النظام التعليمي الأميركي هي "المسؤولة عن 30٪" من هذه الزيادة بعد عام 1978 في عدم المساواة. [173]

العولمة

في حين توافق الاقتصاديين الذين درسوا العولمة كان لها تأثير الواردات، توقيت نمو الواردات لا يتطابق مع نمو عدم المساواة في الدخل. والصين هي أكبر مصدر في العالم لل وصانع المنتجات المصنعة ولكن كان دخل الفرد في عام 2007 سابع واحد أن للولايات المتحدة. بحلول عام 1995 وبلغ مجموع الواردات من السلع المصنعة من البلدان ذات الأجور المنخفضة أقل من 3٪ من الناتج المحلي الإجمالي للولايات المتحدة. [174]

لم يكن حتى عام 2006 أن الولايات المتحدة تستورد المزيد من السلع المصنعة من البلدان ذات الأجور المنخفضة (النامية) من ذات الأجور المرتفعة (متقدم) الاقتصادات. [175] زيادة عدم المساواة خلال عقد 2000-2010 وليس بسبب ركود الأجور لأقل العمال المهرة، ولكن بسبب تسارع دخل أعلى 0.1٪. [174] ويقدر الكاتب تيموثي نوح أن "التجارة"، والزيادات في الواردات هي المسؤولة عن 10٪ فقط من "الاختلاف الكبير" في توزيع الدخل. [173]

هجرة

و قانون الهجرة والجنسية لعام 1965 زيادة الهجرة إلى أمريكا، وخاصة من غير الأوروبيين. [85] بين عامي 1970 و 2007، نمت نسبة المولودين في الخارج من سكان أميركا من 5٪ إلى 11٪، ومعظمهم لديهم مستويات التعليم الدنيا و الدخل من الأميركيين المولودين. ولكن مساهمة هذه الزيادة في المعروض من العمالة منخفضة المهارة يبدو انه تم متواضعة نسبيا. ذكر أحد التقديرات أن الهجرة خفضت متوسط ​​الدخل السنوي من "المتسربين من المدرسة الثانوية" من مواليد ("الذين تتطابق تقريبا لأفقر العاشرة من القوى العاملة") بنسبة 7.4٪ 1980-2000. كان الانخفاض في الدخل من العمال المتعلمين أفضل أقل بكثير. [85] ويقدر الكاتب تيموثي نوح أن "الهجرة" هي المسؤولة عن 5٪ فقط من "الاختلاف الكبير" في توزيع الدخل. [173]

التغيرات في حساب الدخل

أحد المراقبين الذي ينكر أن دخل الأسرة أصبحت أكثر تفاوتا هو ألان رينولدز ، زميل بارز مع معهد كاتو . أعلنت Reyonlds أن عدم المساواة في الدخل هو جلب الوهم الإحصائية عن التغيرات التقنية في قانون الضرائب التي تغير ما يحصل على المبلغ دخل إلى دائرة الإيرادات الداخلية وما دخل لا. [67] [176] وقد انتقد هذا الادعاء بأنه " جبل الخفايا الإحصائية يصعب متابعة، في كثير من الأحيان لا صلة لها بالموضوع، وأحيانا خاطئة تماما " [177] أو "الفكرية ثلاثة بطاقة مونتي ". [178]

يشير رينولدز إلى أن جميع البيانات التي تم جمعها لحساب يستند التفاوت في الدخل على عوائد الضرائب الاتحادية. لم يتم تضمين الدخل ليس على الإقرارات الضريبية في البيانات. وليس من المستغرب، مطلوب ما الدخل وليس مطلوبا أن يتم الإبلاغ قد تغير. قبل إلى 1980s، لم الفائدة في السندات البلدية وخيارات الأسهم التنفيذية لا تحتاج إلى الإبلاغ عن الدخل الخاضع للضريبة. [179] بالإضافة إلى ذلك، العديد من الشركات كما أودع C-بالشركات وبالتالي دخلهم لم تظهر على عوائد الضرائب الفردية. بعد تشريعات الإصلاح الضريبي عام 1986 والتخفيضات الضريبية في عهد الرئيس ريغان، تحول العديد من الشركات إلى كونه S-الشركات وبالتالي دفع معدل ضريبة الدخل الشخصية بدلا من معدل الضريبة على الشركات. [180] ونتيجة لهذه التغيرات وغيرها وأثناء و بعد في 1980s بدأ الكثير من الدخل الجديدة لتظهر على الإقرارات الضريبية من كبار أصحاب الدخول التي تم حقا حصل طوال الوقت. لهذا السبب فإنه ليس من المستغرب أن الدراسات التي قام بها Pikkety / سايز وغيرهم تظهر معظم الزيادة في حصة أعلى 1٪ 'ق من الدخل السنوي التي تحدث في الفترة 1986-1988. وعلاوة على ذلك، بدأت حسابات الضرائب المؤجلة لإظهار اختفاء الدخل من العوائد لأصحاب الحسابات لأنها ظهرت في 1980s. وأظهر الاحتياطي الفيدرالي دراسة عام 2001 أن 5.5٪ فقط من أعلى الأصول 1٪ 'ق عقدت في حسابات الضرائب المؤجلة، في حين عقدت 14.5٪ من إجمالي موجودات المئين 50-95 في الضرائب الحسابات المؤجلة. [181] مدفوعات التحويل هي أيضا إلى حد كبير تجاهل من قبل معظم الدراسات، ولكن ارتفعت نسبة من دخل استيعاب من 5.9٪ في عام 1970 إلى 14.2 في المائة في عام 2004. [182] هذه المدفوعات تذهب عادة إلى انخفاض الدخل الأسر، وبالتالي غيابهم جعلت باطراد الإحصاءات أكثر وأكثر معيبة على مر السنين. حجة رينولدز هو أن التغييرات قد قضت على الدخل من الوسط بينما تضيف دخل إلى الأعلى، مما أدى إلى تفاقم الوضع إحصائيا ولكن في الواقع المتغير قليلا إلى لا شيء.

السياسية والمعيارية والمؤسسية

النقاد التغير التكنولوجي كتفسير ل"الاختلاف الكبير" من مستويات الدخل في أمريكا [22] إشارة إلى السياسة العامة والسياسة الحزبية، أو "الاشياء فعلت الحكومة، أو لم يفعل". [183] ​​ويقولون هذه لديها أدى إلى وجود اتجاه لانخفاض معدلات عضوية النقابات العمالية وما ينتج عنها من تناقص نفوذ سياسي، وانخفاض الإنفاق على الخدمات الاجتماعية، وإعادة توزيع الحكومة أقل.

الأحزاب السياسية ورؤساء

العلوم السياسية لاري بارتلز وقد وجدت علاقة قوية بين حزب الرئيس وعدم المساواة في الدخل في أمريكا منذ عام 1948. (انظر أدناه) [164] [184]

دراسة نمو سنوي متوسط ​​الدخل قبل الضريبة 1948-2005، [185] ويبين أنه في ظل بارتل الرؤساء الديموقراطيين (من هاري ترومان إلى الأمام)، كانت أكبر المكاسب الدخل في أسفل سلم الدخل ومدبب قبالة كما ارتفع الدخل. تحت الرؤساء الجمهوريين، في المقابل، كانت المكاسب أقل كثيرا ولكن ما كان هناك نمو يتركز نحو الأعلى، تهوي كما ذهبت إلى أسفل سلم الدخل. [151] [186]

يلخص نتائج بارتلز، والصحفي تيموثي نوح المشار إليها إدارات الرؤساء الديموقراطيين بأنه "ديمقراطي في العالم"، وإدارات الحزب الجمهوري باسم "العالم الجمهوري":

الديمقراطيون في العالم، وزيادة الدخل قبل خصم الضرائب 2.64٪ سنويا للفقراء والطبقة المتوسطة الدنيا، و2.12٪ سنويا لمن الطبقة المتوسطة العليا وغنية. لم يكن هناك اختلاف كبير. بدلا من ذلك، ضغط الكبير الاتجاه الدخل المساواة التي سادت خلال 1940s، و1950s، وو 1960s استمر إلى وقتنا الحاضر، وإن كان من ذوي الدخل تتقارب بسرعة أقل من ذي قبل. الجمهوريون في العالم، وفي الوقت نفسه، ارتفع الدخل قبل خصم الضرائب 0.43 في المئة سنويا للفقراء والطبقة المتوسطة الدنيا، و1.90 في المئة لمن الطبقة المتوسطة العليا وغنية. لم فقط الاختلاف الكبير يحدث، بل كان أكثر متباينة إلى حد كبير. أيضا من ملاحظة: في الديمقراطيون العالم زيادة الدخل قبل خصم الضرائب بشكل أسرع مما كان عليه في العالم الحقيقي ليس فقط لالمئين 20 ولكن أيضا ل40، 60، 80 و. كنا جميعا أكثر ثراء وأكثر مساواة! ولكن في العالم الجمهوريون، وزيادة الدخل قبل الضريبة أبطأ مما كان عليه في العالم الحقيقي ليس فقط لالمئين 20 ولكن أيضا ل40، 60، 80 و. كنا جميعا أكثر فقرا وأقل على قدم المساواة! أنتجت الديمقراطيين أيضا نمو الدخل هامشيا أسرع من الجمهوريين في المئين 95، ولكن الفرق لم يكن كبيرا من الناحية الإحصائية. [183]

نمط توزيع النمو يبدو أن نتيجة لمجموعة كاملة من السياسات و

بما في ذلك ليس فقط توزيع الضرائب والفوائد ولكن أيضا موقف الحكومة تجاه النقابات، سواء الحد الأدنى للأجور يرتفع، إلى أي مدى الحنق الحكومة بشأن التضخم مقابل أسعار الفائدة عالية جدا، الخ، الخ [151]

نوح يعترف دليل على هذا الارتباط هو "ظرفية بدلا من المباشرة"، ولكن ذلك هو "دليل على أن التدخين هو السبب الرئيسي لسرطان الرئة". [183]

وفقا لعلماء السياسة جاكوب هاكر وبول بيرسون الكتابة في الكتاب الفائز يحصل على كل شيء سياسة ، وجلبت التحولات السياسية الهامة على ليس من قبل الحزب الجمهوري ولكن من خلال تطوير نظام سياسي حديثة وفعالة، وخاصة الضغط ، من قبل كبار العاملين وبصفة خاصة المسؤولين التنفيذيين في الشركات وقطاع الخدمات المالية. [188] نهاية من 1970s شهدت تحولا في السياسة الأميركية بعيدا عن التركيز على الطبقة الوسطى، مع، أكثر فعالية بكثير، جماعات الضغط العدوانية وممولة جيدا جديدة وجماعات الضغط يتصرف نيابة عن فئات الدخل العليا. التنفيذيين القضاء بنجاح أي قوة التعويضية أو الإشراف على مديري الشركات (من التقاضي خاصة ومجالس الإدارة والمساهمين، و هيئة الأوراق المالية والبورصات أو النقابات العمالية). [189]

وجاء نجاح الصناعة المالية من دفع بنجاح لتحرير الأسواق المالية، مما يسمح أكثر ربحا كثيرا ولكن أكثر من ذلك بكثير الاستثمارات المحفوفة بالمخاطر والتي كانت خصخصة المكاسب في حين التنشئة الاجتماعية الخسائر مع عمليات الإنقاذ الحكومية. [190] (المجموعتين شكلت حوالي 60٪ من top 0.1 percent of earners.) All top earners were helped by deep cuts in estate and capital gains taxes, and tax rates on high levels of income.

Arguing against the proposition that the explosion in pay for corporate executives — which grew from 35X average worker pay in 1978 to over 250X average pay before the 2007 recession [191] — is driven by an increased demand for scarce talent and set according to performance, Krugman points out that multiple factors outside of executives' control govern corporate profitability, particularly in short term when the head of a company like Enron may look like a great success. Further, corporate boards follow other companies in setting pay even if the directors themselves disagree with lavish pay “partly to attract executives whom they consider adequate, partly because the financial market will be suspicious of a company whose CEO isn't lavishly paid.” Finally “corporate boards, largely selected by the CEO, hire compensation experts, almost always chosen by the CEO” who naturally want to please their employers. [192]

Lucian Arye Bebchuk, Jesse M. Fried, the authors of Pay Without Performance , critique of executive pay , argue that executive capture of corporate governance is so complete that only public relations, ie public `outrage`, constrains their pay. [193] This in turn has been reduced as traditional critics of excessive pay—such as politicians (where need for campaign contributions from the richest outweighs populist indignation), media (lauding business genius), unions (crushed) — are now silent. [194]

In addition to politics, Krugman postulated change in norms of corporate culture have played a factor. In the 1950s and 60s, corporate executives had (or could develop) the ability to pay themselves very high compensation through control of corporate boards of directors, they restrained themselves. But by the end of the 1990s, the average real annual compensation of the top 100 CEO's skyrocketed from $1.3 million—39 times the pay of an average worker—to $37.5 million, more than 1,000 times the pay of ordinary workers from 1982 to 2002. [157] Journalist George Packer also sees the dramatic increase in inequality in America as a product of the change in attitude of the American elite, which (in his view) has been transitioning itself from pillars of society to a special interest group. [195] Author Timothy Noah estimates that what he calls “Wall Street and corporate boards' pampering” of the highest earning 0.1% is “responsible for 30%” of the post-1978 increase in inequality. [173]

Decline of unions

Union membership in the United States from the Great Depression to current day. (Source: Union Membership Trends in the United States , Table A-1 Appendix A for 1930 to 2000; Bureau of Labor Statistics for 2005 and 2010.)

The era of inequality growth has coincided with a dramatic decline in labor union membership from 20% of the labor force in 1983 to about 12% in 2007. [196] Economists have traditionally thought that since the chief purpose of a union is to maximize the income of its members, a strong but not all-encompassing union movement led to increased income inequality. Given the increase in income inequality of the past few decades, either the sign of the effect must be reversed, the magnitude of the effect small, or a much larger opposing force overridden it, since unionization has decreased in that period. [197] [198]

However more recently research has shown that unions' ability to reduce income disparities among members outweighed other factors and its net effect has been to reduce national income inequality. [198] [199] The decline of unions has hurt this leveling effect among men, and one economist (Berkeley economist David Card ) estimating about 15-20% of the “Great Divergence” among that gender is the result of declining unionization. [198] [200]

Still other researchers think it is the labor movement's loss of national political power to promote equalizing “government intervention and changes in private sector behavior” has had the greatest impact on inequality in the US. [198] [201] Timothy Noah estimates the “decline” of labor union power “responsible for 20%” of the Great Divergence. [173]

How much tax policy change over the last thirty years has contributed to income inequality is disputed. In their comprehensive 2011 study of income inequality ( Trends in the Distribution of Household Income Between 1979 and 2007 ), [150] the CBO found that,

The top fifth of the population saw a 10-percentage-point increase in their share of after-tax income. Most of that growth went to the top 1 percent of the population. All other groups saw their shares decline by 2 to 3 percentage points. In 2007, federal taxes and transfers reduced the dispersion of income by 20 percent, but that equalizing effect was larger in 1979. The share of transfer payments to the lowest-income households declined. The overall average federal tax rate fell.

According to journalist Timothy Noah, “you can't really demonstrate that US tax policy had a large impact on the three-decade income inequality trend one way or the other. The inequality trend for pre-tax income during this period was much more dramatic.” [183] Noah estimates tax changes account for 5% of the Great Divergence. [173]

But many — such as economist Paul Krugman — emphasize the effect of changes in taxation — such as the 2001 and 2003 Bush administration tax cuts which cut taxes far more for high-income households than those below — on increased income inequality. [202]

Part of the growth of income inequality under Republican administrations (described by Larry Bartels) has been attributed to tax policy. A study by Thomas Piketty and Emmanuel Saez found that

Large reductions in tax progressivity since the 1960s took place primarily during two periods: the Reagan presidency in the 1980s and the Bush administration in the early 2000s. [203]

During Republican President Ronald Reagan 's tenure in office the top marginal income tax rate was reduced from over 70 to 28 percent, high top marginal rates like 70% being the sort in place during much of the period of great income equality following the “Great Compression”. [183] While the bottom marginal rate for the bottom fell from 14 to 11 percent. [204] However the effective rate on top earners before Reagan's tax cut was much lower because of loopholes and charitable contributions. (See Saez & Piketty, “How Progressive is the US Federal Tax System? A Historical and International Perspective” </ref> [205] President Ronald Reagan's 1981 cut in the top regular tax rate on unearned income reduced the maximum capital gains rate to only 20% — its lowest level since the Hoover administration. [206]

During the Republican George W. Bush administration, the tax rate on capital gains and qualifying dividends — a disproportionate source of income for top earners — fell to 15% — less than half the 35% top rate on ordinary income. [207] President Bush's veto of tax harmonization has also been attributed to rising inequality, as this would have shut down offshore tax havens. [208]

One study [210] found reductions of total effective tax rates were most significant for individuals with highest incomes. (see “Federal Tax Rate by Income Group” chart) For those with incomes in the top 0.01 percent, overall rates of Federal tax fell from 74.6% in 1970, to 34.7% in 2004 (the reversal of the trend in 2000 with a rise to 40.8% came after the 1993 Clinton deficit reduction tax bill ), the next 0.09 percent falling from 59.1% to 34.1%, before leveling off with a relatively modest drop of 41.4 to 33.0% for the 99.5–99.9 percent group. Although the tax rate for low-income earners fell as well (though not as much), these tax reductions compare with virtually no change—23.3% tax rate in 1970, 23.4% in 2004—for the US population overall. [210]

The study found the decline in progressivity since 1960 was due to the shift from allocation of corporate income taxes among labor and capital to the effects of the individual income tax. [210] [211] Paul Krugman also supports this claim saying, “The overall tax rate on these high income families fell from 36.5% in 1980 to 26.7% in 1989.” [212]

From the White House's own analysis, the tax burden for those making greater than $250,000 fell considerably during the late 1980s, 1990s and 2000s, from an effective tax of 35% in 1980, down to under 30% from the late 1980s to present. [213]

Many studies argue that tax changes of S-type Corporations confound the statistics prior to 1990. However, even after these changes inflation-adjusted average after-tax income grew by 25% between 1996 and 2006 (the last year for which individual income tax data is publicly available). This average increase, however, obscures a great deal of variation. The poorest 20% of tax filers experienced a 6% reduction in income while the top 0.1 percent of tax filers saw their income almost double. Tax filers in the middle of the income distribution experienced about a 10% increase in income. Also during this period, the proportion of income from capital increased for the top 0.1 percent from 64% to 70%. [214]

Effects of race and gender

The black/white gap in median family income is about 3% smaller today than it was in 1979, a lack of progress that may be dismaying but excludes the disparity from explaining any part of the 30-year growth of inequality. [24]

Gender disparity in income has also improved in during the last three decades. The gap in the median annual income between men and women working full-time has declined from 40% to 23%. [24]

منذ عام 1967 وقد ارتفع عدم المساواة بالنسبة للأسر وللعاملين بدوام كامل من كلا الجنسين، ولكن خصوصا للعمال من الرجال. (انظر الجدول أعلاه) قد ارتفع الدخل الشخصي بشكل كبير للعاملات منذ عام 1953، وأقل من ذلك بالنسبة للعمال الذكور، التي ركدت خلال 1970s 1980s الدخل، و 1990s. [111]

ومن غير الواضح ما إذا كان قد قاد الزيادة الهائلة في عدد النساء في قوة العمل ودخل المرأة إلى مزيد من عدم المساواة (على سبيل المثال العائلات كاسب المزدوج يسبب زيادة عدم المساواة). وفقا لمكتب الإحصاء، اعتبارا من عام 2005، كان 42٪ من جميع الأسر في الولايات المتحدة و 76٪ من تلك الموجودة في الشريحة العليا اثنين أو أكثر من ذوي الدخل . [132] [136] ولكن بالنظر إلى الدراسات التجريبية، ودراسة البنك المركزي العماني "الاتجاهات في توزيع دخل الأسرة "، وجدت" نتائج مختلطة "من تأثير الأسر كاسب المزدوج" مع التقديرات حسب الفترة المدروسة واستخدام منهجية ". ووجدت الدراسة أيضا أن مستوى عدم المساواة المنزلية مع الأطفال و(nonelderly) الأسر بدون أطفال كانت "متطابقة تقريبا". [216] نمو الأسر وحيدة الوالد قد أدت إلى انخفاض الدخل ولكن أكثر من ذلك وقعت قبل عام 1980، وفي السنوات الأخيرة زادت نسبة النساء الذين يعملون في الواقع الذين هم الآباء واحد. [85]

أهمية عدم المساواة

المعلقين والاقتصاديين والسياسيين لا توافق على مسألة الزيادة في عدم المساواة في أمريكا أو أهميته. بين الاقتصاديين وغيرهم من الخبراء معظم نتفق على أن عدم المساواة في الدخل المتزايد أمريكا هو "مقلقة للغاية"، [24] ظالم، [157] يشكل خطرا على الديمقراطية / الاستقرار الاجتماعي، [217] [218] [219] و / أو حتى علامة تراجع الوطنية. [195] القلق يمتد حتى إلى مثل أنصار (أو المؤيدين السابقين) من دعه يعمل الاقتصاد والممولين من القطاع الخاص.

السابق الاحتياطي الفيدرالي رئيس مجلس إدارة ألان غرينسبان ، ذكرت إشارة إلى تزايد عدم المساواة: "ليس هذا هو النوع من الشيء الذي مجتمع ديمقراطي - المجتمع الديمقراطي الرأسمالي - لا يمكن أن يقبل حقا دون معالجة" [24] بعض الاقتصاديين (ديفيد موس، بول كروغمان) يعتقدون قد تكون مرتبطة الاختلاف الكبير للأزمة المالية في عام 2008. [220] [221] مدير المال ويليام ه. الإجمالي ، العضو المنتدب ل شركة بيمكو ، انتقد تحول في توزيع الدخل من العمل إلى رأس المال وراء بعض من النمو في عدم المساواة التي لا يمكن تحملها كما، قائلا:

“even conservatives must acknowledge that return on capital investment, and the liquid stocks and bonds that mimic it, are ultimately dependent on returns to labor in the form of jobs and real wage gains. If Main Street is unemployed and undercompensated, capital can only travel so far down Prosperity Road.”

He concluded: “Investors/policymakers of the world wake up – you're killing the proletariat goose that lays your golden eggs.” [222] [223]

On the other side of the issue are those who have claimed that the increase is not significant, [224] that it doesn't matter [219] because America's economic growth and/or equality of opportunity are what's important, [21] that it is a global phenomenon which would be foolish to try to change through US domestic policy, [225] that it “has many economic benefits and is the result of … a well-functioning economy”, [220] [226] and has or may become an excuse for “class-warfare rhetoric”, [224] and may lead to policies that “reduce the well-being of wealthier individuals”. [71] [220]

Consumption and debt

Arguing that income inequality is not significant because inequality of consumption is less are Will Wilkinson of the libertarian Cato Institute and other conservatives. Wilkinson states that “the weight of the evidence shows that the run-up in consumption inequality has been considerably less dramatic than the rise in income inequality,” and consumption is more important than income. [227] According to Johnson, Smeeding, and Tory, consumption inequality was actually lower in 2001 than it was in 1986. [228] [229]

The CBO agrees that household consumption numbers show more equal distribution than household income but finds the data do not “adequately capture consumption by high-income households” as it does their income. [230] Other studies have not found consumption inequality less dramatic than household income inequality. [73] [231]

Others have disputed the importance of consumption over income, as consumption in excess of income usually means debt, [220] and a “growing body of work” suggests that income inequality has been the driving factor in the growing household debt [73] [232] as middle income earners go deeper into debt trying to maintain what once was a middle class lifestyle. Between 1983 and 2007, the top 5 percent saw their debt fall from 80 cents for every dollar of income to 65 cents, while the bottom 95 percent saw their debt rise from 60 cents for every dollar of income to $1.40. [73] Economist Krugman has found a strong correlation between inequality and household debt in America over the last hundred years. [233]

Deep debt may lead to bankruptcy and researchers Elizabeth Warren and Amelia Warren Tyagi found a fivefold increase in the number of families filing for bankruptcy between 1980 and 2005. [234] The bankruptcies came not from increased spending “on luxuries”, but from an “increased spending on housing, largely driven by competition to get into good school districts.” Intensifying inequality may mean a dwindling number of ever more expensive school districts that compel middle class—or would-be middle class—to “buy houses they can't really afford, taking on more mortgage debt than they can safely handle”. [235]

Public attitudes

The growth of inequality has provoked a political protest movement—the Occupy movement —starting in Wall Street and spreading to 600 communities across the United States in 2011. Its main political slogan — “ We are the 99% ” — references its dissatisfaction with the concentration of income in the top 1%.

A 16 December 2011 Gallup poll found a decline in the number of Americans who felt reducing the gap in income and wealth between the rich and the poor was extremely or very important (21 percent of Republicans, 43 percent of independents, and 72 percent of Democrats). [236] In 2012, several surveys of voters attitudes toward growing income inequality found the issue ranked less important than other economic issues such as growth and equality of opportunity, and relatively low in affecting voters “personally”. [237] [238] In 1998 a Gallup poll found 52% of Americans agreeing that the gap between rich and the poor was a problem that needed to be fixed, while 45% regarded it as “an acceptable part of the economic system”. In 2011, those numbers are reversed: Only 45% see the gap as in need of fixing, while 52% do not. However, there was a large difference between Democrats and Republicans, with 71% of Democrats calling for a fix. [236]

In contrast, a national survey by the Pew Research Center for the People & the Press, [239] found that respondents' sense of unfairness about taxes centered on the perception that wealthy Americans were not paying their fair share of taxes; 57% say this is what bothers them most about the tax system, an increase of 6% over a poll taken in March 2003. [240] A more recent poll found about two-thirds of Americans now believe there are “strong conflicts” between rich and poor in the United States. [241] [242]

Opinion surveys of what respondents thought was the right level of inequality have found Americans no more accepting of income inequality than other citizens of other nations, but more accepting of what they thought the level of inequality was in their country, being under the impression that there was less inequality than there actually was. [243] Dan Ariely and Michael Norton show in a study (2011) that US citizens across the political spectrum significantly underestimate the current US wealth inequality and would prefer a more egalitarian distribution of wealth. [244] Joseph Stiglitz in “The Price of Inequality” has argued that this sense of unfairness has led to distrust in government and business. [245]

Impact on democracy and society

A study by Larry Bartels found that Senate votes were more responsive to the opinions of high income groups and were less and even negatively responsive to the opinions of middle and lower class groups. [246]

Economists Jared Bernstein and Paul Krugman have attacked the concentration of income as variously “unsustainable” [218] and “incompatible” [219] with real democracy. American political scientists Jacob S. Hacker and Paul Pierson quote a warning by Greek/Roman historian Plutarch : `An imbalance between rich and poor is the oldest and most fatal ailment of all republics.` [217]

Two journalists concerned about social separation in the US are Robert Frank who notes that:

Today's rich had formed their own virtual country .. [T]hey had built a self-contained world unto themselves, complete with their own health-care system (concierge doctors), travel network (Net jets, destination clubs), separate economy. .... The rich weren't just getting richer; they were becoming financial foreigners, creating their own country within a country, their own society within a society, and their economy within an economy. [247]

and George Packer ,

Inequality hardens society into a class system … Inequality divides us from one another in schools, in neighborhoods, at work, on airplanes, in hospitals, in what we eat, in the condition of our bodies, in what we think, in our children's futures, in how we die. Inequality makes it harder to imagine the lives of others. [195]

Economist Joseph Stiglitz argues that hyper-inequality may explain political questions such as why America's infrastructure is deteriorating,as a result of the reduction in broadly beneficial public investment and support for public education, [248] or its recent relative lack of reluctance to engage in military conflicts such as the 2003 invasion of Iraq. Top earning families wealthy enough to buy their own education, medical care, personal security, and parks, have little interest in helping pay for such things for the rest of society, and the political influence to make sure they don't have to. So too, the lack of personal or family sacrifice involved for top earners in the military intervention of their country — their children being few and far between in the relatively low-paying all-volunteer military — may mean more willingness by the American government to wage war. [249]

The relatively high rates of health and social problems ( obesity , mental illness , homicides , teenage births , Incarceration , child conflict, drug use) and lower rates of social goods ( life expectancy , educational performance, trust among strangers , women's status , social mobility , even numbers of patents issued per capita), in the US compared to other developed countries may be related to its high income inequality. Using statistics from 23 developed countries and the 50 states of the US, British researchers Richard G. Wilkinson and Kate Pickett have found such a correlation which remains after accounting for ethnicity, [250] national culture [251] ), and occupational classes or education levels. [252] Their findings, based on UN Human Development Reports and other sources, locate the United States at the top of the list in regards to inequality and various social and health problems among developed countries. [253] The authors argue inequality leads to the social ills through the psychosocial stress , status anxiety it creates. [254]

Disagreeing with this focus on the top earning 1% and urging attention to the economic and social pathologies of lower income/lower education Americans, is conservative journalist David Brooks . Whereas in the 1970s, high school and college graduates had “very similar family structures”, today, high school grads are much less likely to get married and be active in their communities, and much more likely to smoke, be obese, get divorced, or have “a child out of wedlock.” [255]

The zooming wealth of the top one percent is a problem, but it's not nearly as big a problem as the tens of millions of Americans who have dropped out of high school or college. It's not nearly as big a problem as the 40 percent of children who are born out of wedlock. It's not nearly as big a problem as the nation's stagnant human capital, its stagnant social mobility and the disorganized social fabric for the bottom 50 percent. [255] [256]

Contradicting most of these arguments, classical liberals such as Friedrich Hayek have maintained that because individuals are diverse and different, state intervention to redistribute income is inevitably arbitrary and incompatible with the concept of general rules of law, and that “what is called 'social' or distributive' justice is indeed meaningless within a spontaneous order”. Those who would use the state to redistribute, “take freedom for granted and ignore the preconditions necessary for its survival.” It is not great wealth but government and that gives power to control others in liberal democracies such as the United States. [257] [258] [258]

Opportunity, growth and equality

Conservatives and libertarians such as economist Thomas Sowell , and Congressman Paul Ryan (R., Wisc.) [259] argue that more important than the level of equality of results is America's equality of opportunity, especially relative to other developed countries such as western Europe.

Economic growth and inequality

In response to the Occupy movement Richard A. Epstein defended inequality in a free market society, maintaining that “taxing the top one percent even more means less wealth and fewer jobs for the rest of us.” According to Epstein, “the inequalities in wealth … pay for themselves by the vast increases in wealth”, while “forced transfers of wealth through taxation … will destroy the pools of wealth that are needed to generate new ventures. [260] Stiglitz on the other hand concludes that moving money from the bottom to the top through income inequality lowers consumption because higher-income individuals consume a smaller proportion of their income than do lower-income individuals (those at the top save 15 to 25 percent of their income, those at the bottom spend all of their income). [261]

Some (while specifically advocating redistribution of income through taxation) have not found a “tradeoff” between greater equality and economic growth; but according to economist Branko Milanovic , while traditionally economists thought inequality was good for growth

“The view that income inequality harms growth—or that improved equality can help sustain growth—has become more widely held in recent years. … The main reason for this shift is the increasing importance of human capital in development. When physical capital mattered most, savings and investments were key. Then it was important to have a large contingent of rich people who could save a greater proportion of their income than the poor and invest it in physical capital. But now that human capital is scarcer than machines, widespread education has become the secret to growth.” [262]

“Broadly accessible education” is both difficult to achieve when income distribution is uneven and tends to reduce “income gaps between skilled and unskilled labor.”

Economic sociologist Lane Kenworthy has found no correlation between levels of inequality and economic growth among developed countries, among states of the US, or in the US over the years from 1947 to 2005. [263] Jared Bernstein found a nuanced relation he summed up as follows: “In sum, I'd consider the question of the extent to which higher inequality lowers growth to be an open one, worthy of much deeper research, perhaps along some of the lines noted above. [264]

Some researchers have found a connection between “leveling” higher marginal tax rates on high income earners, and higher rates of employment growth. [265] [266] [267]

Mobility during a lifetime

Strong “ intra-generational ” or individual economic mobility between the strata of rich, middle class and poor means both that (1) a high level of inequality of annual income is made irrelevant by a more even distribution of lifetime income, and (2) however extreme the earnings at the top, they are not out of reach for the poor (or middle income) but ambitious. [20]

Sowell claims mobility is robust.

An absolute majority of the people who were in the bottom 20 percent [of income] in 1975 have also been in the top 20 percent at some time since then. Most Americans don't stay put in any income bracket. At different times, they are both “rich” and “poor” — as these terms are recklessly thrown around in the media. [...] There are of course some people who remain permanently in the bottom 20 percent. But such people constitute less than one percent of the American population, according to data published by the Federal Reserve Bank of Dallas in its 1995 annual report. Perhaps the intelligentsia and the politicians have been too busy waxing indignant to be bothered by anything so mundane as facts. [21]

According to Thomas A. Garrett, studies examining quintiles of wealth levels may provide a misleading picture. [71] For example, a US Treasury study of the period from 1996 to 2005 found that “[l]ess than half (40% or 43% depending on the measure) of those in the top 1 percent in 1996 were still in the top 1 percent in 2005. Only about 25 percent of the individuals in the top 1/100th percent in 1996 remained in the top 1/100th percent in 2005.” [268]

Other have not found individual mobility so fluid. A 2007 study (by Kopczuk, Saez and Song in 2007) found the top population in America “very stable” and “not mitigated the dramatic increase in annual earnings concentration since the 1970s.” [269]

Economist Paul Krugman , attacks conservatives for resorting to “extraordinary series of attempts at statistical distortion”. He argues that while in any given year, some of the people with low incomes will be “workers on temporary layoff, small businessmen taking writeoffs, farmers hit by bad weather”—the rise in their income in succeeding years is not the same 'mobility' as poor people rising to middle class or middle income rising to wealth. It's the mobility of “the guy who works in the college bookstore and has a real job by his early thirties.”

Studies by the Urban Institute and the US Treasury have both found that about half of the families who start in either the top or the bottom quintile of the income distribution are still there after a decade, and that only 3 to 6% rise from bottom to top or fall from top to bottom. [20]

On the issue of whether most Americans do not stay put in any one income bracket, Krugman quotes from 2011 CBO distribution of income study

Household income measured over a multi-year period is more equally distributed than income measured over one year, although only modestly so. Given the fairly substantial movement of households across income groups over time, it might seem that income measured over a number of years should be significantly more equally distributed than income measured over one year. However, much of the movement of households involves changes in income that are large enough to push households into different income groups but not large enough to greatly affect the overall distribution of income. Multi-year income measures also show the same pattern of increasing inequality over time as is observed in annual measures. [16]

In other words, “many people who have incomes greater than $1 million one year fall out of the category the next year — but that's typically because their income fell from, say, $1.05 million to 0.95 million, not because they went back to being middle class.” [16] [270]

Mobility between generations

Several studies have found the ability of children from poor or middle-class families to rise to upper income — known as “upward relative intergenerational mobility” — is lower in the US than in other developed countries [271] — and at least two economist have found lower mobility linked to income inequality. [23] [24]

The Great Gatsby Curve.png

In their “Great Gatsby” curve, [23] White House Council of Economic Advisers Chairman Alan B. Krueger and labor economist Miles Corak show a negative correlation between inequality and social mobility. The curve plotted “intergenerational income elasticity”—ie the likelihood that someone will inherit their parents' relative position of income level—and inequality for a number of countries. [24] [272]

In the words of journalist Timothy Noah

you can't really experience ever-growing income inequality without experiencing a decline in Horatio Alger -style upward mobility because (to use a frequently-employed metaphor) it's harder to climb a ladder when the rungs are farther apart. [24]

Aside from the proverbial distant rungs, the connection between income inequality and low mobility can be explained by the lack of access for un-affluent children to better (more expensive) schools and preparation for schools crucial to finding high-paying jobs; the lack of health care that may lead to obesity and diabetes and limit education and employment. [271]

Krueger estimates that “the persistence in the advantages and disadvantages of income passed from parents to the children” will “rise by about a quarter for the next generation as a result of the rise in inequality that the US has seen in the last 25 years.” [24]

    • “Among the industrial democracies where income inequality is increasing, it's much worse in the United States than it is almost anywhere else. Among 34 nations recently surveyed by the OECD, the United States got beat only by Turkey, Mexico, and Chile. That's as measured by the Gini coefficient, and including taxes and government transfer payments.”
