After the subprime debacle I can't look at any financial institutions or markets as being anything other than a facade for what's really going on behind the scenes. Was the whole event just rigged to make some rich and powerful person even richer? Maybe some trader was approached with this mistake scenario. Billions in wealth is created and destroyed by one person pressing a b or an m on a keyboard. I'm not really comfortable with our entire society being dependent on the actions of elite traders and back room deals.
