Not sure about that. Labor costs are lower in China and the CCP is strongly incentivized to keep enough jobs around for humans to maintain their own hold on power.

Labor costs are lower, but rising, and already high enough that automation can be appealing.

The Chinese government is also pretty good at finding things for people to do, so I doubt that's a factor. Go to any big park in a city and see how many people are sweeping up leaves, or guarding a building/area that isn't particularly secure.
