China is developing fast, I agree, but at what cost? After 30 years, what core technology and brands do we have? If you invest in stocks, there is a similar question, what is the moat Chinese economy has? If you can't answer this question, It just means Chinese economy can go down hills pretty quickly.
The big question is why? Why we have to pollute the env after we all know what happened before in early capitalism? Is this really necessary? Why after so many years of dev, we do not have our own teches and brands? ...
In my opinion, a lot of these lies in politics, and you can't wish away the problems.
