The gap between revenue, and debt only keeps growing, it's growing at a rate of 4% relative to GDP per year (revenues at ~18%, debt at ~22%), and the lines are diverging with debt growing faster than revenues.
This debt accruance will eat more and more of the budget, less money for all the expenses, diminished levels of public services, less money for infrastructure projects at a time when your infrastructure needs quite a lot of renovation; less money for education, so on and so forth.
At some point it has to give, without reigning in this increasing divergence between debt, and revenues the USA will have to print money to either service interests or basic public services... Inflation might not become hyperinflation but definitely won't be on the 2% target when the burden of interest payment gets really bad.
