There is no feasible scenario where tax revenues will allow the US government to pay a 39 Trillion, soon to be 40 Trillion debt. And paying the debt its not even in discussion right now.
What is in discussion, are the multiple, very feasible, and very realistic scenarios, where an increase in interest rates, and a run from the dollar...Will force the US government to spend over 80% of the tax revenue, JUST TO SERVICE the debt interest....
