My post had two paragraphs. The first tried to explain that it does not necessarily have to be a zero-sum game. The second paragraph tried to explain that, even if you do see it as a zero sum game, trade between two parties, or trade in general, can give you benefits over ones who are not part of the trade. Obviously I am trying to describe this in simple terms without writing a book. But i do think the board game analogy holds even though it is very simple.
