By "stuff" you mean income, right? You don't mean wealth?

I did more googling cause I'm interested in this stuff and was trying to figure out what the hell you're talking about:

Quote:

The top 20 percent of earners saw their share of pre-tax income rise from 54.8 percent to 55.7 percent, from 2000 to 2006. During that same period, their share of federal income taxes increased from 81.2 percent to 86.3 percent.

I couldn't find anything on the top 1%, but I didn't look that much...
