"Collapse" is a strong word and even narrowed to "American" society I'm not sure what you would count as collapse. I don't think it's impossible that America could lose it's economic advantage within 10 years, but is that the same as society collapsing?

Or do you just mean American democracy ? It's hard to tell where the various groups and institutions might draw their lines on that. But democracies aren't a law of nature, so perhaps.

Caveat: if someone presses the nuclear trigger all bets are off. I wouldn't rule that one out, but it seemed inevitable back in the 70s so here's to hoping.
