As for bailouts: How much sense bailing out car companies makes is something the brits here should know: None at all, they will fail anyway later, but then of course the money is already spent.
Darwin's theory applies to economics too. If a company isn't fit enough or doesn't find it's niche to prosper in, it's a goner and should be left to die. Throwing good money after bad usually is not a smart thing to do.

Back to the original question:
Capitalism will not have to return, because it won't fall in the first place. I hope it will become a little bit less of a rat's race and that politicians and other decisionmakers will realize that greed shouldn't be the only force that counts.
But let's not forget that the last 20 to 30 years have brought hundreds of millions of people all around the world a better life, and capitalism was what made it possible.
