Govt. debt has been used to pay for high military spending etc. It has happened before many times and can happen again. A better way to solve these problems could be to not just throw money at them but build preventative systems.

> if we're already subsidizing low wage jobs with social programs like food stamps

I imagine by not having to pay as much for social programs, like food stamps. We're already paying for social programs indefinitely.

That is basically the plan, yes. "Modern Monetary Theory" is that USD-denominated debt is free because you can print the dollars to pay it back at any time.

Spend what's needed, then take in what's needed to balance it out, through a combination of taxes and debt.

The new normal should be a combination of moderate deficit spending (nothing like the COVID stimulus packages - those are special crisis spending level events) and significant tax increases for the wealthy (think 1950 level), plus wealth taxes for the ultra-wealthy.
