Paying $10 million for artwork and never looking at it makes a person a douche. The person is paying eight figures to deprive someone else of having it-- nothing more. It's not "supporting the arts". It's being a hypercompetitive shitfuck.
Paying $50 million for trophy real estate instead of investing it into better transportation (the only long-term solution to the real estate problem in New York and Silicon Valley) makes a person a douche.
Using a private 747 for casual transportation, logging an unconscionable ecological footprint through the unnecessary combustion of hydrocarbons in enormous amounts, makes one a douche.
Developing a tight social network to keep global society exclusive, closed and impoverished is a douche move.
Corrupting the U.S. political system and getting the world's most powerful nation into an unwinnable War of Corporate Enrichment (Iraq) is a douche move.
Morally speaking, the tip-top upper classes of the U.S. owe their lives to us in the cognitive 1 percent. They are deep in moral debt to us, and what keeps us from collecting is that we have more interesting things to do (in technology, where we can make positive-sum contributions to the world). We have the persuasive capability and the technological know-how to rise up and take them out, Paris 1793 style. We don't, because for enough of us, life remains pretty good. We're not "among them", and they constantly remind us of this fact; but we can work in technology, live pretty well, and generally control our own destinies. If that ever changes, though, those people need to watch the fuck out.
