helping. >> i think this explains what is going on with people when they think about libertarians are selfish. if you are on the left you probably believe your policies are the only expression of benevolence. you probably think as libertarians disagree with your policies they must only care about your pocket books. that doesn't make sense one because we have real arguments of whey the policies don't work. advocacy is cheap. if i advocate we have a 90 percent marginal tax rate on all income over 100,000 dollars if i advocate that that doesn't cost anything. if i give money to charity. >> government should have a bigger anti government policy. >> you have the warm glow of altruism when you generate that. >> you care when you put your money where your mouth because it costs something. when you are giving 90 percent of your income away or if you have 10 percent you are not showing you care.
