I don’t have a problem with guilt about money. The way I see it is that my money represents an enormous number of claim checks on society. It’s like I have these little pieces of paper that I can turn into consumption. If I wanted to, I could hire 10,000 people to do nothing but paint my picture every day for the rest of my life. And the GDP would go up. But the utility of the product would be zilch, and I would be keeping those 10,000 people from doing AIDS research, or teaching, or nursing. I don’t do that though. I don’t use very many of those claim checks. There’s nothing material I want very much. And I’m going to give virtually all of those claim checks to charity when my wife and I die.
