I went to an engineering university and I like numbers, so here's some numbers I just ran for you guys (sources at the bottom):
2007 US Federal personal income tax revenue by household income:
Households making over $400,000 - $757.9 billion
Households making between $150,000 and $400,000 - $181.5 billion
Households making between $90,000 and $150,000 - $101.2 billion
Households making between $55,000 and $90,000 - $48.4 billion
Households making under $55,000 - $8.8 billion
Now, the 2007 tax revenue from corporate taxes:
$370.2 billion.
Yeah, the rich don't pay their fair share. Mmmmkay. Yeah, "we" paid for all those roads and schools.
