Economic growth is not ever going to go back to 6% sustained growth. Look at S Korea's growth curve before and after 2000. Once you out of the middle income range, a lot of the low hanging fruit for fast growth is gone. The amount of total increase needed for each percentage of growth is three times higher than it was a decade ago, and the amount of investment needed to generate growth is substantially higher.
China is no longer cost competitive in labor intensive manufacturing, which means a lot more people are going to have to find work in service industries. Natural consequence of moving up the value chain and becoming an advanced, high income economy.
If you compare to the US, then you see a lot higher proportion of the workforce holds college degrees in the US, and a lot more college degree holders in the US are working in service / gig jobs that do not really require college degrees. This is a natural consequence of developing into an advanced, high income economy. Due to high wages and incomes, a lot of labor intensive jobs are just no longer economically viable, so you have more people driving Uber or delivering Doordash.
The fact of the matter is, true STEM talent anywhere in either the US or China gets scooped up in an instant. I can guarantee you there is a shortage of STEM talent in China. Doesn't mean every STEM graduate has the necessary ability and skills to fill those jobs. So what's so wrong for them to work as delivery drivers or taxi drivers? At least they aren't saddled with tens of thousands of student debt like their American counterparts.
I've read How Asia Works too - I know how countries develop.
The fact remains, private FAI from Jan-May was -0.1% vs Shanghai lockdowns in 2022 as an easy layup of a comparable. I am really curious, how are STEM grads to find jobs (STEM or Service jobs) if POEs do not invest to create jobs?
