US has more arable land than any other country. That is a baseline. Even on subsistence farming it can sustain its current population. It has an extremely stable and friendly northern neighbor that can as well. Together they control estimated 500 bb oil (including frackables).
It is too big a country for socialists to control.
Income and quality of life are already down substantially compared with the rest of the planet vs. 1990s.
Probably a worst case is Argentina plus white flight, followed by excessive corruption and mismanagement.
The rest depends on whether the next imperial power is China or new Europe. If China, shit will be bad for a while. If Europe, see Argentina.
