how you think your adopted home country should fix it?
Adopted is a good word. America is a cruel step-parent.
Regarding what to do with the debt... I don't know. Elect Bill Clinton again?
The debt is so huge now, that it doesn't seem practical to actually concern oneself with paying it off. It just won't ever be paid off, all things staying equal.
No amount of fiscal discipline and cutting pork will dig you out of this hole, the good old fashioned way.
So I think the answers are probably:
1) Inflation - Pretty much print the problem away. Pay it all off at the expense of the average American's buying power. It's been done before, in the US and in other places. Argentina is sort of a champion in that sport, when it comes to its peso liabilities.
2) Default - just call a spade a spade, and make investors and savers feel super dumb. It might cause all sorts of apocalyptic consequences, however it will also provide a clean break with the problem of debt. Since there's no better place to invest anyway, the pathetic investors will come crawling back on their knees asking to buy new tranches of Treasuries.
I think that's it. Of course, AI could cause some kind of fantastic shift in productivity and growth will skyrocket, and you'll just simply grow out of the problem - but I wouldn't bank on that.
