Page "Distribution of wealth" Paragraph 19

According to the Congressional Budget Office, between 1979 and 2007 incomes of the top 1 % of Americans grew by an average of 275 %.

During the same time period, the 60 % of Americans in the middle of the income scale saw their income rise by 40 %.

Since 1979 the average pre-tax income for the bottom 90 % of households has decreased by $ 900, while that of the top 1 % increased by over $ 700, 000, as federal taxation became less progressive.

From 1992-2007 the top 400 income earners in the U. S. saw their income increase 392 % and their average tax rate reduced by 37 %.

In 2009, the average income of the top 1 % was $ 960, 000 with a minimum income of $ 343, 927.
