Paul Krugman has the answer here and it ain't pretty.
Here’s what the numbers say about percentage gains in after-tax income from 2003 to 2005:
Bottom quintile: 2%
Next quintile: 2.4%
Middle quintile: 3.9%
Fourth quintile: 3.7%
Top quintile: 16%
Top 10%: 20.9%
Top 5%: 27.7%
Top 1%: 43.5% [!!!!!--Emphasis by J. Miller]
It was a boom, all right — but only for a few people.
Disgusting, but not surprising. Who in their right minds has ever thought that the people in the Bush Administration give a damn about anybody other than people like themselves? This is just sad confirmation of what most of us already knew. But it's good to be reminded.
