We'll just pay more in taxes and yes, we'll borrow more.
At some point, we'll have to inflate our currency just like Argentina.

GDP is a formula. GDP = C + I + G + (X - M)
Consumption, Investment, Govt Spending, (exports - imports).
You can spend your way to GDP, but taxes reduce Investment.
There is no answer. This is the fundamental truth that no one can talk about or accept and certainly not campaign on.
