Well then, where are we going to get all the uranium to keep your poor(bottom class) paranoid self feel safe.
The problem is that we are in a double deficit, we have used up our surplus and gone into record debt and we import about $617 billion a year more than we export. Is isolationism going to fix that??
We have generated a huge debt at about $2 billion a day. China and Japan, with higher exports hold a lot of american currency. Consider the South Koreans with about $200 billion, when they considered trading it in on a stronger currency caused the dollar to drop 3%. What's going to happen as we continue on the path is that eventually China and Japan will favor stronger currencies (where's that leave us??).
