The US dollar would bust because they are printing paper MORE than ever and nothing to back it up.

the fact that nothing backs the dollar in no way means it has no value.

The dollar is supposed to represent the amount of gold held by its country...

that's incorrect.

Lets say if a middle east country decieded to go back to a gold standard, it would bring the US to its knees.

it would not affect the value of the dollar. other things affect the value of the dollar.

I like your take on how a stock would be paid out by adopting a different currency should the dollar go bust. I was not aware of that.

this only a guess as to what might happen. but some type of currency is needed or we'd soon be back to barter.
