Following up on my earlier post, my brother reminds me that Buffett plans to avoid billions of dollars of estate and capital gains taxes by donating his fortune to charity—suggesting that he believes that the Gates Foundation can better spend his money than the US government can. But Tim Carney points out that Buffett has very much a financial interest in ensuring that Leviathan has a lot of money to spend, as he can make profitable investments by accurately predicting where government largesse will go.
