I have read a lot about human nature. It has actually been the main area of my philosophical studies and still is. Just because some communist say that people were made not to care about themselves quite a while ago doesn’t beat biological discoveries.

Arguments by communists are disregard by all the nations that have had communism in their country (mine as well) and saw it horrifically failing. Communism wants to have everybody equal and everybody with more or less same "wealth" whatever it would be without capital. That is not possible since not every person is worth as much as the other. That is utopia. Communism never worked in any given country for more than few years. And you know why? Because people are selfish. Main argument being “communism works“is a self-killing act. Every system that was yet annexed had selfish people in which fought against each other to have a better position, whatever it was in the system.

You’re arguing that morals are subjective and at the same time your argument is that YOU love people, because love makes YOU happy. That loving is natural to YOU. And I could continue. Just because YOU feel this way doesn’t mean that the all HUMAN BEINGS feel this way, for they are not YOU, but THEM. And THEY can have totally different feelings about that.

Funny thing is that one of the problems tackled in the post is self-voting and you have already up voted yourself for 2 bucks. You wouldn’t be able to live in a world described by you either. You have proved that you’re selfish even more than most users on this platform.
