I agree with this. Not everyone can work on high-value industries. Wages need to keep at pace with cost of living and increase even more in time.Not everyone can enter a higher value add industry and you need to have wages for lower skill jobs like janitorial staff wages track with cost of living increases.
A problem will arise in 10 years time with automation coming strong for these low value jobs though.
We will see what happens then, thats not a China-specific problem
