Economics and game theory tell us that into all systems, a bit of suckage must come. If you take a subversive look at the history of the United States, it would seem that groups of people here all lift themselves out of poverty through a combination of entrepreneurship and shameless graft/cheating/crime. I don't think the US has been free of some kind of group strife / domestic terrorism since the 2nd presidential administration. That's also when one political side accusing the other side of being horrible people who would bring about the end of the nation started.

The older I get, the more Stratfor's geographic interpretation of history and geopolitics makes sense.
