How did the government create the derivatives bubble? Seems like the exact opposite happened: the government massively deregulated things, then just a few years later there was a bubble.

Since the bubble burst, what corrections has the free market made to prevent there isn't another one?

So much of the rhetoric about "free markets" seems to come from looters who resent the government eliminating ways to make money by rent-seeking, collusion and fraud rather than producing useful goods.
