The problem ultimately I think is in trying to discern what ‘undue’ influence is. I think what bothers me about this view is that it pretty much erases the historical fact that 1. Maoist China existed, 2. It survived despite imperialism and aggression from both superpowers, 3. The nationalist bourgeoisie were liquidated after New Democracy properly came to an end in 1954. What made China a success in my view compared to say India is in fact that they realized that the bourgeoisie could never be CURTAILED so much as they had to be abolished, which is why Mao was so paranoid about capitalist roaders propping up - the revolution would never be complete without them being sequestered from society.

In my view, what you have in China is a situation where many of the elites that Mao and the left of the Party disdained are suddenly in a much better situation. As a personal anecdote - I knew kids who joined the Party in college because it meant that they would be able to get better finance jobs. The Party has become a sort of quasi corporate entity in that as an institution it doesn’t have a hostility to capital per se so much as it uses certain language to proclaim that it is against capital’s dominance. But my bet is that of Mao’s: an iota of capitalist influence will eventually corrupt any political project to overthrow it.
