Not offset.

Other way around.

Debt comes from spending, that spending is on stuff, which drives GDP.

So whole concept that we could reduce debt by increasing GDP and tax it, is not how the money actually flows.

This is why in economic downturns, often the best solution is more debt, by more spending. And trying to fix economy by 'austerity' makes things worse.

Of course, also I don't know solution, or what the 'right size' debt should be. Just that it isn't black/white.
