First, in.my opinion, the American Banking system is "hardly" a threat to the Blue Collar masses. Most of us have funds held by insured banks, and unlike those who actually took the risk of non-insured for higher percentages...well, they gambled and lost.
Globally, however, BRICS has -- for the first time ever reported a higher GDP than G7 nations.
THIS, can be a problem for the "dollar". While it's highly unlikely the greenback will see the fate of gutter currencies, the rising strength of BRICS may jeopardize the global acceptance of the greenback.
--- just my two cents.
