Okay - the Great Recession began in 2007. It didn't start overnight, though. In reality, it began several years before that. I would argue that every recession since 1980 all led up to the Great Recession as a result of continuous passing of economic policies under Reagan, Bush, Clinton, and Bush that created more and more income disparity.
Note that the two greatest periods of disparity were right before the Great Depression and right before the Great Recession. Tax policies that help concentrate wealth and reward wealth over work lead to hoarding.
To get the "trickle down" that supply-siders seems to like so much you basically have to force the wealthy to invest and hire.
I agree that the stimulus wasn't done completely properly. However, all Republicans have done is said they wouldn't have done it all. They complained about extending unemployment benefits without paying for it; but want to make permanent the Bush tax cuts without paying for it. They fought legislation that would have eliminated the loophole that left no estate tax for this calendar year, costing the government $25 - $30 BILLION dollars and didn't pay for it.
They are also fighting the bill that will give tax breaks to small business owners who hire and make equipment investments. Not because they dislike the legislation, but because they don't want Democrats to get credit for it. It is their goal to bring this nation to its knees while Obama is in office so they can get their claws back on all three houses and continue funneling money to the wealthy who will continue to pay for their campaigns.
Oh, and by the way:
How Ford and GM Turned a Corner -- Seeking Alpha, there's evidence that the auto bailout (with a little help from Toyota's implosion) is actually working. But of course, we'll just bitch about it because maybe it wasn't perfect.
The economy didn't collapse overnight. It won't be fixed overnight.
