So what? If the dollar collapses, there'll be hyperinflation, and it will act like a jubilee and our debts will be forgiven. Our worthless paper dollars are mostly stored overseas, by people who believe in them more than their own home currency.
Look how strong the dollar has been lately; folks the world over are flocking to it because we have our act together slightly better than the Eurozone.
The only ones with something to fear are the trust fund babies who don't know how to MAKE money/ be productive in a revised economy, and would see Daddy's nest egg shrivel up. Daddy, of course, was some sort of insider trader who cooked the books and grabbed his share when noone was looking. Now that there's "old money" daddy wants to defend what he took out of circulation, so he has us all fighting over gay marriage and other frippery.
