All it takes is for one of these alternate currencies to be backed by something tangible. Don’t doubt that any country that hates the USA would damage itself in order to hurt the USA worse; the USA then becomes the scapegoat.
Unless of course people on here have that much faith in Obama’s fiscal non-policies?
Despite the economic malaise Obama has brought us through, and the constant exaggerated refrain that "we don't make anything anymore, China does" and "China owns us and buys our debt", no other country comes close.
China may make our toys, but we make their medical equipment, aircraft, vehicles and industrial machinery.
I don't believe either the idea that a country would prioritize damaging the USA over their own well-being.
