And what happens then is.. well... nothing... for all their angst on "the left", they've yet to muster the right-wing-hate which would result in a true call to arms.
The civil war speculated about in Wealth and Democracy should happen 15 years from the apparent peak of US dominance. Which is about 11 years away.
Given a 5 year margin of error, that's anywhere from 6-16 years off.
No, I'm not joking. However I'd also give that civil war no better than about 2/3 odds of actually happening, even when I feel pessimistic.
