If your interested in who bankrupt the US, well tally up how much chinese made stuff you have in your house and you'll find your answer.
You, Me, and Wal-mart.
(we all helped Home Depot run every mom&pop hardware store out of business)
A big chunk of the debt is trade deficit, the remainder is Iraq and rebuilding New Orleans. (I'm sorry which other president faced this?) As much as people don't like war it's where most new technologies get developed. It's better to blow stuff up there than the middle of some desert in Arizona.
Mind you I'm not saying GW is a good president, he isn't. However he's been blamed for people paying too much for houses, banking scams and a lot of other factors that have led to our current money crunch.
Iraq, insisting on tax cuts, $15billion in AIDS help for Africa. Yep, He's resposible for these. Not forcing you into a more fuel efficent vehicle than that gas pig SUV your driving, well that's been going on for some time and $5/gal gas will fix that.
It's always easy to blame some CEO or politician and turn a blind eye to the illegals trimming your bushes and rebuilding your bathroom. Our biggest problem has always been lack of accountability and it doesn't stop with the guy at the top.
