Greg Smith doesn't know the half of it.

Smith, now the most famous former Goldman Sachs derivatives salesman on the planet, went off on his former employer in the opinion pages of the New York Times this past week — much to the amazement of nearly everyone — because he claimed that during his 12 years at the firm, the ethics and morals of his co-workers deteriorated so dramatically that he just couldn't take it anymore.

"I can honestly say that the environment now is as toxic and destructive as I have ever seen it," he wrote. "To put the problem in the simplest terms, the interests of the client continue to be sidelined in the way the firm operates and thinks about making money."
