To begin with, it's a revelation to discover that Vin Scully swears like a sailor.
Joe Citizen's pension isn't back and better than ever. Because Joe Citizen also saw a booming stock market in the summer of 2008. Then the fall of 2008 came about, and Joe Citizen realized how volatile and propped up the stock market is he would rather avoid it by investing in lower risk funds or avoiding it entirely.
More importantly, your stock market is part of your economy, but isn't at all a correct indicator about the overall health of your economy. Joe Citizen sees that real unemployment (not imagined) is north of 10 percent at least, average household income is starting to trend downward for the first time in forever, and his son and/or grandson's $160 thousand dollar degree is currently only worth an "unpaid internship."
With regards to hyperinflation, you are the reserve currency, so some other country is going to have to proactively make this happen. A break-up of a currency union is most prevalent. If you have an enemy, or enemies that your are dependent on for manufactured goods, and/or energy, and they all the sudden find you expendable because you aren't buying anything anymore, then hyperinflation becomes a reality.
More importantly is the fact that it just isn't a smart idea to put yourself in this position to begin with. Your total debt is important. It's a world record, so it's important. Your debt to GDP may not be number one, but it also sucks! You guys are in 20th or so, right? And you just passed Zimbabwe? That isn't a stat to tote around, that's an embarrassment. If you truly are the world's superpower, don't clown around, don't put yourself in a situation when you one day will be at the mercy of others. That isn't a healthy future.
