As usual, Mark Cuban makes a fantastic point--this time, about Bernie Madoff and his investors:
Basically, compared to the average investor, the Madoff investor might end up doing better. In addition, Madoff's investors will be getting tax deductions because of their portfolio "losses." Any way you dice it, Madoff's investors got about the same as the average investor over the last ten years. Yet, no one is trying to bail out the average stock market investor.
I said essentially the same thing here, but Cuban has more stats to support his view.
