The issue is that Mozilo's behavior resulted in personal gains against extreme public losses. It's in our best interest as a society to deter such behavior, while enabling whatever legitimate business Countrywide conducted. How do we best do that? The public at large wins — Mozilo should win, the public at large loses — Mozilo should lose.
I think GP's point is that a $60M fine (against $520M in earnings) is not a an effective deterrent against such antisocial behavior.
