Or is it to secure a well-founded base of power for people regardless of inherited means, in order to provide them with the quality of life and personal development they need?
And how are you gonna do that without an industrial base? It's not about "GDP" or "playing their game", it's about industry being necessary to support a decent life for a large population.
If we're talking about the invasion of a bourgeois army in the service of capital, then it's pretty clear that everyone in its general path will have a common cause of self-defense against it
Will they? There's gonna be a sizable chunk of the population that would probably materially benefit from capitalist restoration, mainly the previous upper classes and their lackeys. Also people with terminal religious/traditionalist brainworms. Also people that don't want to spend a decade in a guerilla war.
For the whole world's sake, I am glad that the CPC in the 30s did not follow the directive that "the substance of a socialist revolution is seizing industry and cities, not building up a rural power base and the means of subsistence".
1930s rural China looked absolutely nothing like for example rural America today, it's not even the least bit comparable. Back then peasants were the absolute majority of the population, nowadays this isn't true at all.
