> For me, it's coming down to a fundamental difference or distinction: Those who believe in a zero-sum-gain world, and those who believe in a net-sum-gain world. I fall into the latter camp. In other words, I believe that by sharing and cooperating, we all can advance. People like to say this, but they are only okay with sharing things they approve of. By your logic, aren't you morally obligated to let me have something of yours if I ask for it? I'm not criticizing cooperation, just the idealism that falls apart in practice. The best course of action is a complex blend of the two camps you mentioned.
