First of all, I think your thesis is an example of "agent bias". Humans have a tendency to scapegoat, to blame
someone for events rather than impersonal forces.
Based on what I have read about monetary crises, financial panics, and recessions (past and present), I find it hard to accept the thesis that if we only had fewer "douchebags" in the world, that we could avoid all problems. Financial flows would still induce bubbles, and bubbles would still play on mob psychology. Devaluing a currency would still push GDP above its natural level, and require a period of readjustment.
Furthermore, the corporate culture of the 2000s and the 1990s was far, far, far more professional and less "douchebaggy" than what I've heard of the 80s. Why, you can get fired for sexual harassment nowadays, which would have been impossible 20 years ago.
Again the system you describe where "douchebags" rule is far different from my experience in the system. You say that non-"douchebags" cannot climb the corporate hierarchy because it is stacked with "douchebags". Your crude term does not describe the majority of the MBAs, CEOs, MDs, associates, CFOs, accountants, lawyers, and others that I had the pleasure to be acquainted with, although there was a minority of people that I certainly would not like to ever see again.
Lastly, I suspect you are getting upvotes merely for using rhetoric that makes teenagers giggle, which I find sad. Such a juvenile word choice lowers your credibility, because it appeals to the inner snickering child, and not the logical mind. An observer is left to conclude that your point could not stand on its own without the use of crude emotional appeals.
I cannot help but think that reddit has arrived.
