US individual income taxes are about $1.8T a year (the $250B number in the link is refunds). There's also about $1.2T in payroll taxes paid by employers, $500B in corporate taxes, and a few smaller things like tariffs and interest, etc., adding up to a little over $3.5T total revenue per year.

The current gross national debt is just shy of $20T. So, that's about 6x the annual government revenue.

In theory, national debt is "good debt" like a home mortgage, and having a home mortgage worth about 6x your salary seems pretty healthy.
