Income inequality in the United States - Wikipedia, the free encyclopedia

A 2011 study by the CBO[16] found that the top earning 1 percent of households gained about 275% after federal taxes and income transfers over a period between 1979 and 2007, (although this number has decreased somewhat since 2007 as a result of the Great Recession [17]). From 1992 to 2007 the top 400 earners in the U.S. saw their income increase 392% and their average tax rate reduced by 37%.[18] The share of total income in America going to the lower earning 80 percent of American households (also after federal taxes and income transfers) has dropped to less than 1/2 in 2007.
