Reply #6: I wonder if floating the dollar against oil would be the last straw.

As far as I can tell, the only reason the dollar is still hanging by its fingernails is that the rest of the world takes a hit if the dollar (and American economy) collapses. So they continue to prop it up. But at some point, the pressure becomes irresistable, and foreign economies will have to float the dollar, and stop purchasing our debt, etc.

Something is going to break that log jam. It's just a question of what.
