If trump wins and America can't defeat his senile version of fascism, then it's already on the death bed waiting for the next republican to take power...
trump is the best authoritarian we're going to get, he's easy mode, the republicans will get someone worse, someone who has the ability to think beyond his next shit.
It's not going to get better only worse...
If we had an unlimited timeline I'd buy that, the problem is climate change will make all but struggle inevitable in ~75 years at the rate we're destroying it.
Famine, water wars, and billions of climate migrants will destroy any hope of an egalitarian revolution...
