The Occupy Wall Street protesters have focused attention on rising income inequality in the United States, and they are right to do so.

Perspectives from expert contributors.
Income and wealth disparities have reached levels not seen in the United States since the Roaring Twenties. And the concentration of income and wealth contributed to the speculative excesses that brought on the 2008 financial crisis (see Robert Reich’s “Aftershock” and Raghuram Rajan’s “Fault Lines”).
According to a recent report by the Congressional Budget Office, rising income inequality is a long-term trend that began in the late 1970s and strengthened during the last two decades. The report confirms the protesters’ belief that the rising gap between the income of the top 1 percent and the income of everyone else is a major factor behind escalating inequality.
In the last 20 years, inequality has been largely a story of a small elite – not just the top 1 percent, but the top 0.1 percent – pulling away from everyone else in every source of household income: labor income, capital income and business income.
The top 1 percent’s share of national income has also been rising in most other advanced industrial countries, but it is by far the largest and has grown the most in the United States (see Jacob Hacker and Paul Pierson’s “Winner-Take-All Politics”).
Why have incomes of those in the top 1 percent soared? Their occupations provide some clues. From 1979 to 2005, nonfinancial executives, managers and supervisors accounted for 31 percent of the top 1 percent, medical professionals for 16 percent, financial professionals for 14 percent and lawyers for 8 percent.
Together, executives, managers, supervisors and financial professionals accounted for 60 percent of the increase in the top 1 percent’s income, with a widening compensation differential between those in the financial sector and those in other sectors of the economy after 1990.
Superstar athletes, actors and musicians, often portrayed among the super-rich, accounted for about 3 percent of the top 1 percent from 1979 to 2005, far less than the less glamorous people (mostly men) who lead and advise America’s businesses.
Researchers have identified several reasons for the rapid growth in incomes for the occupations that make up most of the top 1 percent, including “winner take all” technical innovations that have changed the labor market for superstars in all fields; increases in business size and complexity; a growing premium for highly specialized skills; changes in the forms of executive compensation, including the rise of stock options and weaknesses in corporate governance; and the increasing size of the financial sector.
All of these factors have played a role, but there is no definitive evidence on their relative significance.
Growing inequality in labor compensation played a major role in increasing income inequality between the top 1 percent and the rest of the population from 1979 to 2007. Over the period, however, both the growing inequality in business income, including income from small firms, partnerships and S corporations, and in capital income in the form of dividends, interest and capital gains, as well as the rising share of these forms of income in household income, played a more significant role, especially after 2000.
According to the Congressional Budget Office, from 2002 to 2007 more than four-fifths of the increase in income inequality was the result of an increase in the share of household income from capital gains, with the remainder the result of an increase in other forms of capital income.
Capital and business income are much more unevenly distributed than labor income and have become more so over time. Capital gains income is the most unevenly distributed — and volatile — source of household income.
Congressional Budget OfficeThe concentration index is a measure of the inequality of income from different sources among households. The index ranges in value from zero to one, with zero indicating complete equality in the distribution of an income source among households and 1 indicating complete inequality (for example, if one household received all of the income from that source).
The top 0.1 percent earns about half of all capital gains, and such gains account for about 60 percent of the income of the top 400 taxpayers.
Large cuts in federal tax rates on capital and business income have been very beneficial to the top 1 percent over time. In 1978, a Democratic Congress and a Democratic president reduced the top tax rate on most long-term capital gains to 28 percent from about 35 percent. It was reduced again to 20 percent in 1981 and then raised back to 28 percent in 1987, where it remained for a decade.
While serving as President Clinton’s national economic adviser, I led a study by his economic team of the likely effects of reducing the rate. We concluded that a cut would decrease future tax revenue, would contribute to rising inequality and would not increase saving and investment as its advocates asserted. Despite these warnings, in 1997 the president agreed to cut the rate to 20 percent, as part of a budget compromise with the Republican Congress.
Then, with Democratic support, President Bush reduced the tax rate on capital gains and other forms of capital income to a record low of 15 percent in 2003. Under the “carried interest” provisions of United States tax law, this rate also applied to fees earned by hedge fund and private equity managers, a rapidly rising cohort within the top 1 percent.
As a result of these changes, along with President Bush’s across-the-board cuts in income tax rates, federal taxes as a share of household income fell for the top 1 percent. Over all, the Bush tax cuts were the largest — not only in dollar terms but also as a percentage of income — for high-income households and increased the concentration of after-tax income at the top. Far from curbing escalating inequality, the Bush tax cuts exacerbated the problem.
While the federal tax code is still progressive, its progressivity has eroded, with a significant percentage of the richest now paying a much lower tax rate than the merely rich and the middle class. (Warren E. Buffett pays a lower tax rate than his secretary because most of her income comes in the form of wages that are subject to both federal income tax and the payroll tax while most of his income comes in the form of capital gains and dividends that are taxed at 15 percent and that are not subject to the payroll tax.)
A credible plan to reduce the long-run deficit requires a significant increase in revenue. Polls indicate that the majority of Americans, like the Wall Street protesters, believe that higher taxes on the rich are warranted both to reduce the deficit and to contain mounting inequality. I agree.
Restoring the top income tax rates and capital gains and dividends tax rates to their levels under President Clinton, as President Obama has repeatedly proposed, would be useful first steps. Taxing some carried interest as ordinary income would make the tax system more efficient and curtail outsize compensation in the financial sector. Adding a progressive consumption tax would augment revenue while encouraging saving and discouraging spending on luxury goods, both by the very rich and by those down the income ladder struggling to keep up.
The majority of Americans, like the Wall Street protesters, also believe the corporate tax rate should be raised. I disagree.
For reasons I discussed in an earlier Economix post, I believe that this rate should be reduced – a position advocated by both President Obama and former President Clinton in his new book. Raising tax rates on capital gains and dividends to the levels under President Clinton would curb the growth of income for the top 1 percent and could finance a substantial cut in the corporate tax rate that would bolster wages and job opportunities for American workers.
