I get that regulators are worried about job losses. They should be. But the long-term job losses are going to be much greater when investors around the world lose confidence in the U.S. financial system because they recognize that individuals do not face punishment for criminal activity. The individual incentive not to commit crime on Wall Street now is almost zero. Even the worst of the worst – like, say, a certain unindicted co-conspirator in an evolving insider trading case – is only threatened with individual prosecution after years of monstrous and obvious market manipulation, resulting in massive profits that he'll almost certainly get to keep most of, by the way, if previous settlements are any guide.
