"This year's numbers show that both the income share earned by the top 1 percent and the tax share paid by the top 1 percent have reached all-time highs. In 2005, the top 1 percent of tax returns paid 39.4 percent of all federal individual income taxes and earned 21.2 percent of adjusted gross income, both of which are significantly higher than 2004 when the top 1 percent earned 19 percent of AGI and paid 36.9 percent of federal individual income taxes."

"Wall Street and Main Street: What Contributes to the Rise in the Highest Incomes?"

Abstrect: "We consider how much of the top end of the income distribution can be attributed to four sectors – top executives of non-financial firms (Main Street); financial service sector employees from investment banks, hedge funds, private equity funds, and mutual funds (Wall Street); corporate lawyers; and professional athletes and celebrities. Non-financial public company CEOs and top executives do not represent more than 6.5% of any of the top AGI brackets (the top 0.1%, 0.01%, 0.001%, and 0.0001%). Individuals in the Wall Street category comprise at least as high a percentage of the top AGI brackets as non-financial executives of public companies. While the representation of top executives in the top AGI brackets has increased from 1994 to 2004, the representation of Wall Street has likely increased even more. While the groups we study represent a substantial portion of the top income groups, they miss a large number of high-earning individuals. We conclude by considering how our results inform different explanations for the increased skewness at the top end of the distribution. We argue the evidence is most consistent with theories of superstars, skill biased technological change, greater scale and their interaction." Source: Social Science Resource Network
