the way to understand the “Barney Frank did it” school of thought about the crisis is that it’s an attempt to turn a huge defeat for conservative ideas into a win. The reality of the financial crisis was that deregulation - which was part of a broader rightward shift in policies that played a large role in creating rapid growth in income inequality - led to an economic catastrophe of the kind that just didn’t happen during the 50 years or so when we had effective bank regulation. So the right’s answer is to claim not just that the government did it, but that it caused the crisis by its attempts to reduce inequality! It’s kind of a masterstroke, in an evil way.
