Just a thought, Uncle Sam is printing so much money, and because the currency is such international it is everywhere. And when the world is flooded with the currency, what if none of the countries is spared from hyperinflation?

When that happens, we can forget about economic performances, foreign investment, asset classes, bungalow, etc etc.

Social unrest will prevail until a certain force strong enough to gain control over the mass public. Social stability and economies may take months or even years to be restored (not recovered, but just to put orders back in place again).

I suspect, during that period, barter system or commodity-based exchange system will be commonly acceptable until everybody settle with a common way of exchange. Perhaps, back to commodity-backed (gold/silver) currency. Basically start all over again and evolve, and naturally let the history repeat itself again in 50-100 yrs time?
