The way I see it humans are individuals and yet we are social beings. In a way our life shouldn't be controlled by other people but neither can it be selfishly driven by our greed. We need to give constantly, but we don't need to recieve everything that is given to us. Society judges what is right and what is wrong, they give you the parameters for you to live by. We are singular, we need to understand that the only person we need to please is ourselves, and yet we can't completely neglect that helping other people is one of the most rewarding things ever.
The book talks about how people who were "givers" eventually became more successful, not always though, the "givers" either were really successful or at the bottom of the pyramid. "Takers" ruled the middle with the "Mergers". Which role do you choose?
