That is what I believe. The US is economically bankrupt, which would show up as a complete collapse if the money borrowing were to ever slow down for more than a few months.
Indeed, we are coming to end-game VERY soon anyway. You see this in the lack of GDP growth even with additional dollars. It used to be we got something like a 10:1 goose in GDP by deficit spending. That is now flat to, by some estimates, actually negative. Trees don't grow to the sky; we will be forced to shutter all the foreign military bases soon enough; coming home with neither "victory against all the bad guys", nor peace and freedom at home. It seems likely to look like Afghan/Vietnam withdrawal times 100,000 AND DOME HOME TO ROOST if it isn't handled gracefully..
