Sooo ... Sources ? Cause e.g. if you look up Chinas Debt/GDP ratio you will find ~90℅ ( https://worldpopulationreview.com/country-rankings/debt-to-gdp-ratio-by-country )

If you look for the average incone you will find ~ 10000 yuan ( https://wage.is/china/ )

42k seems incredibly unlikely: 42k yuan would down to 6.2k dollars a month - or ~ 75k a year The chinese laborforce is about 770 Million people ( https://data.worldbank.org/indicator/SL.TLF.TOTL.IN?locations=CN )

In that case wages would be quite a bit bigger than gdp (AS claimed Here) which is essentially impossible

Comparing the average wage claimed Here to gdp/capital claimed here we would also have to assume for Every Worker there are 3 non workers - which again is not compatible with chinese workforce data

What China achived in the last 2 decades is impressive enough AS it is - i dont geht why you feel the need to exaggerate it (unless of course you can Provide sources )
