Billionare investor Warren Buffett just announced he'll give the bulk of his $44 billion fortune to the Gates Foundation to aid health and education, especially in poor countries.

I liked this quote of his, in the New York Times:

"I love it when I'm around the country club, and I hear people talking about the debilitating effects of a welfare society," he said. "At the same time, they leave their kids a lifetime and beyond of food stamps. Instead of having a welfare officer, they have a trust officer. And instead of food stamps, they have stocks and bonds."
