That is $3000 a year per person, given a U.S. population of 1/3 of a billion.
Seriously though, what does that even mean?
Per capita, we rank fairly low for national debt, which means we should be spending way more per person to maintain and improve our existing infrastructure. HSR when?
A lot of this debt is money we lent to the government via past social security surpluses. The other large debtee are other American organizations, only a small part of this debt is held overseas.
The concept of "national debt" is a joke in the face of cost of living. The overwhelming expense that hamstrings most people is every 30 days is losing 30-50% of their income to rent after they just lost 40% of it to taxes.
This "$3k per person debt" on the other hand is related to printed money largely pocketed by corrupt people in our government - who now will print over $1T dollars in a single go for the latest cause ("keeping the govt open", Ukraine, etc.) - it has nothing to do with what Americans ask for or receive in benefit.
People are over-burdened with excessive living costs and really have to take that hit each month, this so-called debt is a joke. I wish the U.S. would default on the debt already and start replacing government infrastructure with modern technology so our country can operate like a functioning machine again.
How do you service the debt? You print and print. And then that causes more unrest. You can't default and you can't keep rates high enough for long to matter on inflation. Because you have to print to service the debt which only grows with higher rates and time, which you have less of when unrest grows.
