USD is a bigger problem than US debt

The real issue is the quantum of US Dollars in existence since every US Dollar in circulation actually represents a claim against the US Govt., and by extension, the American people. Unimaginable amounts of Petro Dollars and Eurodollars are currently in circulation, the vast majority in the hands of foreigners. I would not be surprised if the u.S. is owned, lock/ stock / Barrel by foreigners. Effectively.
