It's interesting to think about what that kind of money actually does for you. First and foremost, you can retire comfortably. But then, between splurging on luxuries (like an expensive home or two) and investing (particularly indulging in a personal interest, like space), it's not clear what that kind of wealth really does for you. Perhaps it is a social function of giving access to people with similar levels of wealth, and, one would hope, similar levels of talent/intelligence/wisdom. (Or maybe the world sucks and most rich people are just lucky and cunning.) Certainly it puts you in a potent position of advocacy - imagine being able to tell Glen Greenwald, "I love what you're doing so here's $5M to start a media company that supports and expands that."

Idle thoughts.
