What made manufacturing jobs go to China in the first place was the extremely low wages and lack of red tape, worker benefits, safety, bureaucracy, etc...
In the past months wages in China have risen enough to make some US companies return jobs to the US because they were no longer saving money in China. This was predicted to happen at some time around 2015 but we're seeing much earlier. The better the Chinese get paid the less of a reason companies will have for outsourcing in the first place. Why? Because by insourcing manufacturing back to the US businesses have more control, don't have to worry about IP theft, and don't have to wait a month for shipments to come back from China.
Basically:
Chinese are treated like crap = backlash from consumers + bad for workers + but more jobs for the Chinese. Chinese workers treated better = more approval for consumers + better for Chinese workers + but less jobs for China.
