Finance is where the actions of a few individuals have the biggest impact on world utility, right? So we just need a way to compromise their decisionmaking. I think the cheapest way to achieve this would be to run some kind of macho-culture events for financiers, promoting ideas like "staying up all night makes you manlier" and "real bankers drink four shots on their way into the office". Better still, make these things be charity events (charity awake-a-thon anyone?) - spend a small portion of the proceeds on ineffective charity, and reinvest the rest into running more events.
