The issue is, there are still internal Chinese migrants willing to work cheap in China, not as cheap as before but still cheap, especially those from western China. Foreign workers can be imported for political concessions I suppose.
Not happening. Rural localities have already sent most of their youth to cities, even ones from Western China. Whomever could move to the South, did it already over the last 2 decades. Henan for example was the most populous province, but now is a place with mostly middle aged people because of youth outflow.
Sichuan looks relatively young, but people from there don't go South because they have Chongqing, and the industry there is more or less robust on itself.
Limit is only set by human... The days of AI and massive automation is coming and China will start a third economy revolution.
They are really not coming. All of that is in imagination of people who never held a screwdriver in their hands.
But why are so many chinese in these forums generally so scared of foreign workers.
Few years of ideological reeducation in the North East will fix their attitudes. Those people fail to recognise that people ready to go to other side of the globe to do business are already a better selection of their populations, mostly in the prime working age, enough cash to live and not get deported on day one, and useful skills that allowed them to make that cash in the first place.
How China got its Arabs and Jews in the first place? They are all descendants of foreign merchants that settled in China to sell our wares to the world during Tang, Song, and Ming.
Look, I myself don't want China to repeat mistakes of, say, Turkey. Ottomans were for years importing useful foreigners, and tolerating rich Greeks. Then, the new "secular" Turkey (which was in reality ran by a clique of old money elites) spends decades purging them, and the bigger part of its creative and industrialist classes, doing enormous economic harm to itself in the process.
