Follow this link to an article by Economic Policy Institute’s webpage on the State of Working America. It has a great interactive pie chart showing how growth in average income has been shared between the richest 10% and the remaining 90% of the country. For example, from 1970 to 2008 average incomes in the U.S. grew by $12,320, however, ALL GROWTH went to the richest 10%, income for the bottom 90% actually declined!
