this figure rises to a total of $59.1 trillion, or $516,348 per household
This figure is the total projected figure over time, however. For some of those projections, I believe the total is over 75 years. Social security isn't actually going to go red until sometime around 2040. (Medicare is in worse shape--projected insolvency date 2019.) It's true that we've made a lot of promises that current revenues won't cover, but that doesn't mean that our actual national debt should properly reflect all those future liabilities today. the $10 trillion figure is bad enough and is realized, not just projected, i.e., it represents what we've already spent in excess of what we've taken in.
Unfortunately, talking about paying off debts is bad politics, because it has no recognizable constituency. In practical terms, it's everyone's third or fourth priority when everyone only cares about their top two. That's how you get lip service. "Yes, paying off the debt is important, but universal health care is more important." "It would be great to be able to reduce the deficit, but we're fighting a war." No one is actively against paying it down the way people are actively for and against abortion rights, the war, universal healthcare, rail construction, etc. A few rare deficit hawks remain in Congress, but they're an endangered species.
