The most sustainable vision wins eventually. If history has anything to teach us, is that it's full of extremely unpleasant periods between the stable ones. And things aren't looking like they're improving.

If that's the case, then the most sustainable vision gradually devolves into unsustainability.

That's what's happening. Neoliberalism is slowly drifting into fascism, as it has already done multiple times in the past. Maybe what comes after will be actually stable, and not just metastable.

"democracy leads to fascism leads to war" - just watched the movie Eden by Ron Howard

And that vision can be dark or realistic.
