What people seem to refuse to accept is that democrats won't have another chance, any time soon. It's done and gone. Count one or two generations, at a minimum, under the new Epstein class regime, before people may try to rise.
But thinking of it, your estimate might still hold under that premise.
As a European, I have still hopes for the US though. The western world is already reorganizing itself without the US in the center, but we and the world in general still need the US as being more of an ally than an adversary (at the moment, it's more of an adversary to the western world, sadly).
