Can you honestly say that to the people who were buying triple A investments that turned out to be junk thanks to credit default swaps? Who's fault do you think

Can you honestly say that to the people who were buying triple A investments that turned out to be junk thanks to credit default swaps? Who's fault do you think that is? Do you blame sick people for not being smarter than a doctor in diagnosing their own sickness? Do you blame people for dying in a bridge that collapsed because they weren't smart enough to see it was poorly designed? I could go on and on. The point is that Wall Street has somehow become the only place with no accountability, and everyone is supposed to be an expert.
