Every single marxist-leninist state relies on using reactionary tribalism (nationalism) to maintain societal cohesion as they are utterly incapable of actually creating a unified class consciousnes among the populace.
And if the populace did develop class-consciousness they would quickly overthrow the marxist-leninist state and kill off every single member of the party-bureucrat that ruled over them.
Class consciousness will come about naturally as the means of production develop to a point where the Capitalist class increases it's repression as their position becomes obviously pointless to even 80IQ wife beaters.
This is why I'm actually an AI accelerationist. AI is absolutely the technology that makes it pretty fucking obvious "Why do you exist?" a question to swaths of the PMC and Capital class when AI outperforms them in every way.
