well...
You are trying to bring out a point. But if you think about it, who would be happy if we had no corruption. The answer is that noone would be happy. In a perfect world everything would be the same. In a perfect world everyone would like the same things, act the same way, and not in any way want power. In a perfect world nothing at all would happen. Now who would want that? If we dont have corruption there would be no reason for there to be happyness, sadness, or fun. All that we have to do is tell ourself's "what is the truth?" but the only way we would do that is in a perfect world.
