People will continue to deal with GS, despite (maybe even because of) their ever worsening reputation, as long as they can convince themselves that they are the ones who are going to get rich while the other idiots are going to get ripped off. The incentive scheme is similar to that of a slot machine.
My earnest hope is that everyone learns not to trust GS at their word, or at all. And then GS can't find buyers.
Hey, I can dream, right?
