Warren Buffet has made the largest private charitable donation ever, an estimated $37 billion to the Bill and Melinda Gates Foundation. I heard a comment quotes from him on NPR this morning, one of which was very good about children should not be entitled to riches just because of whose womb they came from. I couldn't find it on this great article & interview's page, but I did find this other good one, "a very rich person should leave his kids enough to do anything but not enough to do nothing." He said that back in 1986. His donation will double the assets of the foundation and he will take a seat on their board.
