It's a very similar situation. Without the stimulus, the economy would have remained in recession throughout 2009 and we'd have several million fewer jobs today. If you think that's a better situation, I don't really know what to tell you.
Without the stimulus the bad companies would fail, new companies would prosper, and unemployment would have been under 8% like Obama's advisor said the stimulus would make it.
Doubtful. Without the stimulus, unemployment would likely be 12-13% right now (if not higher).
