It's like this: if you have one piece of cake, and you eat it, that's fine. If you have two pieces of cake, you should probably share some with a friend. But maybe not. Occasionally we could all use two pieces of cake. But if you have a whole cake, and you eat *all* of it, that's not very cool. It's not just selfish, it's kinda sick and unhealthy.
