@cicerone imposter,
ci, too much credit is what caused this mess, in my opinion, so I disagree with your analysis. So much credit was extended, that the money was being loaned to unreliable borrowers, causing the law of unintended consequences to take over, housing prices that went up too fast, and all the rest of the problems either parallel with that or related to that.
The problem is a bit like an accordian, when it became extended so far, then it had to contract, at which point any business (and there were too many of them) relying upon too much credit could not pay other businesses, consumers could not pay off loans and houses, and defaults mounted, which drove more people and businesses to have to contract in size, cut back employees, people cut buying, etc. The problem would not have been as severe if the government had kept its nose out of the housing and property markets, just one example of what had a hand in stimulating this mess.
So continuing or expanding the policies that helped cause this mess is not going to solve the problem in the long run.
