to be succinct, ignorance is ignorance, no matter what rationale you use to support it. You stating that filthy rich people should blow money just because they can, tells me a lot about you as well. It tells me you are the kind of guy likely to place all of your bankroll on one game, lose, and they say, "oh well."
I can think of a lot better ways to entertain yourself and I can certainly think of a lot better ways to gamble with your money.
