GRETCHEN MORGENSON: “The financial system, thanks to dissembling traders and bumbling regulators, is at greater risk than you know.” Bottom line: “We already know that banks of JPMorgan’s size are also too big to be allowed to fail and too big to prosecute. Such banks are too big to regulate and apparently too big to manage. So how much more evidence do we need that banks like JPMorgan are simply too big a risk for taxpayers to bear?”
