People are selfish, why don't they just give me money instead?

People are selfish yes. You are all over the place, yes. As to why we are selfish...that's a very complex question that I could write novels about. Yet at the same time it is very simple. The most simple answer is that it is human nature. It's all just yin and yang. The sun sets but tomorrow it will rise again. Some people are selfish and some are selfless. Some are good and some are bad. That is how the universe balances itself.
