He's better than Baghdad Bob.
I mean seriously the dot-com bubble, the housing bubble, and the stock market bubble, and the bond bubble (which hasn't really started popping yet) all share an underlying cause.

It's not rocket science. It's high school commerce/economics or even primary school common sense and maths.
