The financial crisis was started by government interference in housing and changing of decades old lending and financial rules.

I know that used to be a popular viewpoint but its most vocal claimants are falling quiet for increasingly obvious reasons.

Government is not responsible for proscribing every imaginable ridiculous action that anybody might perform. In this case the bankers lobbied for change that they said would advantage the market and community, then they managed to set the ranch on fire and then they ran away rather than trying to put it out. Nobody made them do that and it is not reasonable to expect government to create laws to prevent people poking their eyes out with a pencil just because it is possible to do it. There has to be a balance between government "interference" as you describe it and an expectation that if allowed, the market and its practitioners will behave rationally. Even Greenspan agrees that the market lacked common sense and wasn't even capable of acting in its own self-interest which is about as dumb as a sentient being can get.
