Earlier quoted context omitted.
I don't have a ton of first hand knowledge on the risk appetite of banks or the effect of banking regulation. But I assert that Matt Levine is very knowledgeable about these things and he disagrees with you. His points are that multiple 10 figure fines, higher capital requirements, and a general culture shift have actually made banks less profitable and less risky, as was intended. EG: https://www.bloomberg.com/view/…
Until you start throwing executives in prison, nothing will change long term. 10 figure fines are nothing compared to how much many Americans lost in the housing market crash. Consider how many people got foreclosed upon improperly. The loss of quality of life (and actual life) due to Wall Street greed is unmeasurable, but surely more than 10 figures.
This idea that the banks foreclosing is somehow a sign of greed boggles my mind. Now, sure there is a bunch of consumer protection around to help 'honest Joe' out when times are tough - but it isn't going to magically stop a crunch point coming where either you keep paying off the loan or you lose the house.
