The theory of John Nash in it's simple form from "A Beautiful Mind" is quite interesting. He proved that if the one acts on behalf of the interest of the group then the results will be better for both the one and the group. Now this isn't just someone's theory or conjecture, it is a proven fact. Now apply this to the world. If each portion (country, religion, etc.) of the world act for the benefit of the world as a whole then the results will be better for the world and that portion as well.
So applying this to economics, credit virtually disappears in meaning since this notion of A loans to B, B loans to C, C owes D, etc. is no longer useful if A, B, C and D are part of the one group. Using Nash's line of thinking, things are probably too fragmented at this point. We have countries, corporations, special interest groups, etc. all acting in their own interest and frequently contrary to the interest of the group of humanity as a whole. For a better and more lasting tomorrow, we should consider how all of these components can act in the interest of the whole.
