Its $104k per person so it could be $500k per taxpayer but that omits corporate taxation-identities. In addition there is tariffs and other government revenues, i.e. land lease, drilling rights, etc.So individual taxpayers don't have to service all that debt. Personal income tax is about 35% of govt revenues.
"The Corporate Tax Rate in the United States stands at 21 percent. Corporate Tax Rate in the United States averaged 32.08 percent from 1909 until 2024, reaching an all time high of 52.80 percent in 1968 and a record low of 1.00 percent in 1910. source: Internal Revenue Service."
If the US dollar was not the reserve currency for the world interest rates could be 1-1.5% higher for US borrowers. IMO the debt is a concern but its not yet dangerous at 122% of GDP. US taxpayers have along ways to go to pay the tax levels of Scandinavian countries. The US rate of 43% is about 10% less than the Nordic countries.
