I definitely agree that Bush spent too much damn money. That's one of my chief criticisms of his presidency.
But Obama certainly made things worse. He showed no signs of fucks given about the deficit during his first four years.

As far as these tax increases go, it's obviously not about fixing the deficit. Imo, they're just going to be used to justify the batshit insane budget proposed next fall. The "fiscal cliff" amounts to fuck-all in terms of government budgeting.
I'm glad we can agree that the tax code is messed up. That's one reason I never wanted to work in that field. No one else in the country likes our current methods except tax professionals (lawyers, accountants, and IRS agents). It's too complex. I don't see it as a sustainable model, and it's due for massive overhaul.
