Most of the people that I've seen taking this position were conservative, free-market capitalists, giving themselves a little "Bad, me!" slap on the wrist. The leftists and socialists are well-read enough to know that the reason loans were backed the way they were is because the regulatory apparatus has been wholly captured by financial players, from regressive legislator campaign funding to the revolving door at regulators, and everything in between. Further, the fallout from 2008 hit most Americans so hard because insitutions leveraged this "in" to warp the shape of the federal and monetary response to the crisis in order to make them whole at everyone else's expense - a course that was not explicitly called for in law (and that some would say, in many cases, violated the duty of responsible parties to uphold the law). The problem remains the banks.
