The $600B annually is about half the annual interest on the $36.93 Trillion Federal debt at an average of 3.4%.

But in the long run, the tariffs are about restructuring the US economy to become a producing nation again. Once that happens economic activity should produce the additional revenues to retire the debt.

It could work. But for that to happen we need a Balanced Budget Amendment so if we are ever stupid enough to elect Democrats again their damage will be limited.
