I disagree a bit. They clearly knew what they were doing was going to be a problem, at least all the engineering managers did - hence they quit.see there is the problem, and should be regulated, and I am not a regulation person.
Regulating the banks didn't stop sub-prime. Regulating firearms hasn't stopped criminals. All regulation does is slow down the good guys. The bad guys cheat anyways. Besides, who was going to write regulations around a sub that never should have been built.
