Chinese workers aren't poorly educated as such, even if those still exist of course. Contrary to popular belief what make China succeed in manufacturing is ample supply of semi-skilled workers. A lot of Chinese factories aren't that sophisticated overall. In a smaller factories equipment might be domestic Chinese or second hand Japanese/Korean equipment. Every few days, or even multiple times an hour, the machines needs help or maintenance. A light will go red and a machine operator will come an poke it for a bit until it works again. Poking a machine a bit is like a revered hobby in the west, if not a $100k job. And you can barely buy a screw retail. All so the rich can get richer through rents.
