we have just been benifiting for a long long time from an extended expansion of the US Money Supply that has been financed by increasing globalization.

The house of cards won't crash until some idiot politician is elected who truely believes in stopping globalization.

I truely believe that Universal Healthcare in the USA also has the potential to stop the Gravy Train.

If you give people free healthcare, then they have no reason to work...

Then the house falls down and stagflation runs wild, meanwhile, the Fed loosens, the dollar declines, dollars rush into the USA in an attempt to buy cheap goods, but with a declining workforce, there is nobody left to manufacture the cheap american goods.
