On a macro scale, the reality of the world is pretty harsh. “Greed” does drive the world. Of course, the “greedy” people surround themselves with other people who help them become successful. And one can only do that if you can create some loyalty, trust, amongst the supporting people, and give these people some benefit in return for their support.

In my book there are two types of “greed”
1) One greed benefits society as a whole
2) The greed benefits few or one

Naturally the first greed creates abundance, and happiness, while the other does not.
