 Look at you, you're pretty pathetic animals. We're weak, we're slow, we have no fangs. What makes us different than any other animal is we're not programmed to survive. You actually have to figure out how to survive. So the most important thing about being human is our capacity to think. Thinking requires freedom. It requires the ability to try stuff out. We need to go out there and live and make decisions, fail sometimes, get back on our feet. So you want a system that protects our ability to think and act on our thoughts. That's capitalism.
