Starting in late 2009, the national debt per capita first exceeded the national income per capita. That trend has only accelerated. I can't say what the consequences will be down the road. Much probably depends on how the same curve plays out in other countries. As always, Japan is the canary in the coal mine.
As of 8/17/2022:
National Income per capita: $64,091
National Debt per capita: $91,295
Numbers do not include state and local debt, corporate debt, or personal debt.
