He (the banker) didn't get rich by just holding the keys, he got rich by getting involved in new tech early (credit default swaps, mortgage backed securities, stated income loans, MERS, etc.). In fact, he helped build something he believes will change the world (easy credit for borrowers, safe high yield investments for teacher's pension funds). Never mind that these innovations lead to a housing bubble, a global financial crisis, the borrowers bankrupt and the teachers eating cat food in their retirements, the banker and all his accomplices think he is a cross between George Bailey and Albert Einstein.

The banker blows a housing bubble, Satoshi blows a bitcoin bubble. I would concede that so far the housing bubble has done far more damage, but if bitcoin "succeeds", that could change.
