While investigators try to determine just how much money investors lost to Bernard Madoff, and regulators wonder how they could have missed such an outragous fraud, I am reminded that economic downturns have a tendency to uncover frauds that have remained hidden during the good times. So, in addition to asking whether capitalism has had its day (see other thread) I wonder what further financial scandals have yet to reveal themselves, where they are taking place, and whether they will match Madoff's pyramid or tower over it.
