I understand the anger, but as the chairman of an influential financial committee, he has to try to instill confidence in the financial system. The financial system is built on trust. If people no longer trust the financial system, it will collapse as people withdraw from the system. It could turn into a self-inducing death spiral. This is what happens with bank runs. In the 1930s, the Fed has found that banks that went under were likely to be as strong if not stronger than banks that did not. In other words, banks collapsed because people became fearful at a specific time and reacted by withdrawing money regardless of the underlying fundamentals of their bank.
