The real problem is that the banks are allowed to take risks without paying the price for these risks when they do not pan out. We have set a precedent that the large financial institutions are too big and too important to fail, and thus they may operate with quasi-impunity knowing that they might have to cut some junior employees/restructure/spin off some divisions in the event of a downturn, but that the revolving door between the public and private realms will always be open, through which both taxpayer money/credibility and new jobs will always flow to those at the top. Nobody will go to jail for being a self-interest optimizing sociopath because our legal and economic system is set up to favor corporations and those with the money to thoroughly defend themselves rather than society as a whole.
