The working-class in the imperial core has a police-state boot on their necks and it's been there for a long-ass time and it isn't going away and will only increase... Give it time.
It's a lot easier to start Naxalbari (and even that lost its goodwill in the few areas they control or controlled, up to now) in a place like India or do a coup in Africa.
It's a lot harder to topple a government like what happened with France in 1968 and even then it was just a bourgeois change of leadership in the long-run, albeit somewhat shaky in the case of Mitterand.
Latinx, Black, Asian, some poor whites, etc. don't want the racist police and prison boot on their neck and that just makes it harder to organize; we need more organization more than anything.
We have too many activist groups and movements strewn all over the country if you check, say, Instagram (and whatever they'll show on Facebook) in the local and maybe state level.
But barely any unity or collaboration.
