Ah, hindsight. I doubt that many people actually predicted exactly what and when it would happen. Just saying "mortgage-based securities will fall" or "the market will go down in 2007/2008" doesn't count. Of course, I don't doubt that some people predicted it in the sense that they took trading positions against the market. But there are always people shorting the market.

Have you actually read any of his books? His style might be a little unusual, but I've never seen any "magical thinking" there.
