People can do crazy stupid stuff no matter how much money they make.
I've seen this a lot in business, especially with Type A entrepreneurs & managers. They start out with the goal to get rich & buy the associated lifestyle toys (big house, shopping sprees for the spouse, nice cars, luxury vacations, etc.), but in doing so, the pursuit of money becomes habit over time. Then when they achieve their goal, they're so used to chasing it that that's what they keep doing. Enough is never enough, I guess because of habit.
Come to think of it, I've seen the same thing in dating, especially with my fellow geeks. We get programmed by TV that girls are to be chased & put on a pedestal, but again, the Type A personalities are the ones who are going out & getting the girl while a lot of geeks perpetually live in the friendzone because they're chasing an idea rather than achieving the goal (i.e. getting a date). But that's a whole different thread :awe:
