I do not think people are naturally selfish or that capitalism makes us selfish. I think selfish is only created out of a perceived lack of resources. The US and its people actually give more than anyone else in the world. I dont see socialism, taking from people to give to others, as genorosity. In fact, Bernie Sanders and many leftist figures in the US give very little to charity compared to people who believe in freedom. Good post, it made me think!
