MLM, or at the very least a revolutionary methodology that highly relies on the workings of MLM, is the single and only path for a revolution in the modern first world and the imperial core.
With deindustrialization, labour / proletariat politics are dead. The working class is dead. There is no longer the traditional revolutionary subject of the 20th century. Instead, slowly, and now ever increasingly, we return to the political dynamics of the 18th and early 19th century - the politics of the impoverished, sans culote riots. A peoples army, unifying all the segments of the underclasses - the hobos, the gig workers, the McWagies, the immigrants - is the only real path for a true socially progressive force in the first world. Starting from communal outreach, from populism, forging bonds from the common impoverished misery and following the Maoist principle of from the people to the people (addressing the real day to day concerns of the masses first and foremost), a real fighting force can be created.
Also, China is nothing more than the new imperialist hagemon. If the old imperial core doesn't fall to a revolution, then it will be reindustrialized, and shall, slowly, once again become the seat of empires, as well as see a return to classical Marxist political practice of working class organisation. However, in case of such a scenario, the MLM path for revolution shall become the only choice in the east, as it too will be forced to deindustrialize as the USA did.
