Yes! The Chinese workers are being exploited by foreign companies/corporations. Basically slavery imo. They could never get by with treating human beings in such a manner at home in their country of origin.
Yes and many of these foreign companies and corporations are American. So are you suggesting the Chinese government arrest these American owners and managers and punish them for their crimes? Of course the American public will be furious and claim that the Chinese government is entirely unreasonable blah blah blah.
The Shanling factory looks pretty good to me:

When a company treats its employees well and they're all happy, we often hear about it because they're "rare". Go to various audio manufacturers site. Some really seem to have a "team" spirit, while others are really a one man show.
