Americans have a lot to barter with, and the coming Social Upheaval will re-value most commodities to reflect our new, sadder reality.
For instance, my neighbor's Jet Ski will be worth nothing, except maybe as parts to create a much-needed water pump, whereas my vegetable patch will reap great rewards later on when we are all sick of government cheese.
That is assuming Obama allows white people accesss to the government cheese.
No, Obama will only let the Rats eat the cheese.
:-P
