Tax dollars really don't pay for things in the US Federal Government.
Deficit spending leading to an ever rising debt is the source of continued spending. When Debt/GDP grows, we're spending ever more money that we don't have.
You're not wrong, but exorbitant deficit spending has its own dire consequences. (eventually) Not that I am telling you anything you don't already know.
What if we just inflate away the debt? Sure, ppl will hate dealing with very high inflation for a few years, and pensioners and whoever buys those trillions of debt will get screwed, but besides that we should be ok?
