Well, there is a sure fire method, and it is the one that will ultimately be used. Hyperinflation. Eight years into hyperinflation could pay off the $19 trillion debt, with my change from Wendy’s.
The economy is so bad that even with all the QE they have barely starved off deflation. Other countries have devalued their currency which does not benefit us. But you’re right good old inflation would solve the problem.
