Would they actually just sit in front of the telly and starve to death if the government checks stop coming? If so, good riddance.
The only hope for our own country is that the Chinese call in all their loans to our irresponsible government. As long as you fund a drug addict, he will get more dependent. We need to be forced to kick the government out of our lives cold turkey.
Treasury bonds can't be called in by the purchaser of the bonds. Over their lives (i.e. until their maturity date), interest payments are made every six months, with the final interest payment coincident with the repayment of principal. Treasury bonds owners can sell their bonds or opt not to buy any more Treasury bonds when their holdings mature. But they can't ask for the early return of their principal.
