More to the point: Marxism is not, and was never meant, to be a way to run a country, only a Factory, Farm or other "means of production".
Interesting.
I always understood Marxism as requiring a complete change in society. Certainly the proletariat cannot seize a factory, farm, or other means of production without the support of society in general. There has to be some sort of drastic social upheaval, a true revolution of the proletariat, to establish the broad consensus that society will now be run along Marxist lines. Private property - capital - is abolished in favor of collective ownership. The investor class is eliminated entirely, along with the bourgeoisie.
My understanding is that where Lenin and Mao went wrong was not in trying to apply Marxism to a whole country, but in trying to apply Marxism artificially. Marx predicted that the worker's paradise would emerge spontaneously from the social conditions of late-stage capitalism. Marxism-Leninism and Maoism held that it would be possible to force the advent of Marxism without waiting for society to evolve naturally into the
prophesied predicted state.
And I don't see how Marxism necessarily means central planning on a national level. Certainly Marx himself envisioned his utopia as nation-spanning, society-spanning, globe-spanning.
Anyway, it is what it is. China had revolutionary Marxism forced on it by Mao and others, and many other indignities besides. Now it is what it has become. Would it have become something else instead, if Chiang Kai-Shek had prevailed? Would it have become a liberal democracy with capitalist markets, in the western model? Or would it have manifested some other form of centrally-governed oligarchic bureaucracy?
We'll never know. But I suspect that, under the skin, the Mao dynasty and the Xi dynasty are of a piece with the Qing and Ming dynasties that preceded them, and the Chiang dynasty that almost was.
Any kind of Central Control is doomed to fail because of lag.
Whereas handling lag seems to be an out of the box feature of capitalistic markets. Ironic.
But I do think it's possible to have a central communist government without going all in on central communist planning. It's just that for some reason whenever communists get hold of a government, they want to do central planning as well. Why is that? They must be bad Marxists, I guess.
I wonder if it has something to do with the capitalist implications of regional or local planning. The workers seize a factory, alright. Now they own it, essentially. If they're allowed to choose their own customers, organize their business to ensure their own local prosperity, it's just capitalism all over again. Private ownership of property, and private decisions by the owners about how to use that property, how to invest the capital it represents. I'm pretty sure that's not what Marx had in mind.
Nor what Mao had in mind.
