A lot of questions here.
First, since our debts are in dollars, we are very lucky. We can simply pay them off with worthless dollars...printed as necessary.
Of course that means the end of the United States being a first-world country. We will NEVER be looked at the same. Instead it will be almost barter as we try to import stuff. We offer dollars, the other countries (especially China) laugh. They want REAL stuff, like highways, federal land, crops, oil. The idea of paying for ANYTHING in dollars will be over.
That’s why I tell EVERYONE to STOCK UP NOW, while the IDIOTS around the world still think that we’ll protect the dollar. We can buy HUGE quantities of REAL items, like Rice or Plasmas, at very low prices...NOW!!!
We do not know when...but soon it will all be over, and what you have in your basement (or attic) will DEFINE how you live for the next decade.
After that, it depends on whether Americans (or Chinese, depends on who’s running this place) figure out where the PROBLEM is...(i.e., liberals). If not - game over.
