Nice charts...unfortunately they only go through 2007. The updated CBO report that I linked adds 2008 and 2009.
Let's try again from the CBO report I linked:
Average before-tax income fell between 2007 and 2009 for households in all income quintiles, but the amount of that decline varied by quintile. The declines in before-tax income were 5 percent or less for households in each of the four lowest income quintiles and 18 percent for households in the top quintile. For households in the top one percent, income fell by 36 percent, reducing their share of before-tax income from 18.7 percent to 13.4 percent.
You can read...right? "between 2007 and 2009", fell 36 percent.
