The truth be told, the way the Fed is structured, I don't know what Congress could do but complain about it, unless they developed the gonads to dismember and do away with it. The though of the US government printing it's own money doesn't sound too good either.
A bust is the only thing that would settle the matter. Reset the clock and start over, ala the Soviet Union.
The debt we know about is untenable, so what could we do if we found out the Fed has used our dollars to create many times that?
