China has the opportunity to build an economy that degrows from consumption patterns that assume a far lower level of industrialization.
It's sad that in their state capitalist philosophy of centralizing power over the means of production, they are still building a lot of inefficient consumerist infrastructure. Without that, the target green capacity could be a lot lower and much easier to achieve.
It is very impressive though that they could hit carbon neutrality only 10 years after the nations that outsourced their carbon-spewing industries to them while staying state capitalist. They're definitely doing a better job than the US, though the EU is probably doing better still.
Thanks for your perspective, I'm glad there are people like you who feel free to openly articulate in support of it. It's sad people are downvoting as disagreement, because I can't imagine them downvoting out of a good faith belief you're not contributing.
A) When the state owns the company, being "non-profit" is just a matter of accounting. And Uber wasn't a public service back when they were operating at a loss. The power structure is far more important, and when "the benefit of the Chinese people" is decided top-down through nonrepresentative means, that's not socialism even if you trust the dictator/oligarchy/overlord/etc. to play nice.
I am genuinely glad your government has given you ample housing, but that doesn't make your relation less one of being owned and managed. (not to say the west is better, just that China isn't good enough either).
B&D) The USSR is one nation, and a centrally industrialized dictatorship at that. As a point of scientific process, how are they supposed to have definitively proven wasteful capitalism is necessary as you claim? Even if they genuinely attempted degrowth, that's just one data point or approach. Different systems that fall under the same bucket can fail or succeed depending on more fine-grained specifics.
Also, the USSR slaughtered millions of small-scale farmers (so-called Kulaks, who happened to largely be Ukrainian) to make way for their industrial megafarms. They were not an example of trying degrowth, they were an example of an industrial centralized dictatorship being embargoed by most of the world.
Your point of not being crushed by the US is well-taken, and maybe Nixon did make an offer China could not refuse at the time. But I think that time has been over for the past 10-20 years. China can defend itself, and even if the military-industrial complex needs mass production to stay on par with the west that does not need to apply to the rest of the economy.
C) Take it from someone who lives in a mature and "prosperous" nation. The fruits of capitalist-style growth suck balls. You're not giving people a better life by building their industrial/living infastructure wrong initially, you're taking them away from family and craft and friendship. All things that threaten those in power, by the way
If you have time, look up Marx' description of societal alienation. He puts it better than I could. And feel free to ask me to look stuff up to.
