"Remember that all tax revenue is the result of holding a gun to somebody's head. Not paying taxes is against the law. If you don't pay your taxes, you'll be fined. If you don't pay the fine, you'll be jailed. If you try to escape from jail, you'll be shot. ... Therefore, every time the government spends money on anything, you have to ask yourself, 'Would I kill my kindly, gray-haired mother for this?'"
