The girl works for a Chinese-owned factory which manufactures goods for an American company's consumption. That is very different than an American-owned factory in China.
There are factories popping up all over China that are owned by Chinese Christians working with Americans that pay salaries much higher than the average wage and that provide safe havens for the Christians to practice their religion there. You can deny this, but if so, you simply do not know what you are talking about and clearly demonstrate that you do not know anyone working in China right now.
Of which, by Chinese Law, there can be no such thing. It has to be done with a Chinese 'partner'.
As for the rest of your contention, the Chinese oppression of Falun Gong is in, what, its 15th year...and the Christians are equally behind the eight ball. If U.S. companies are successfully coordinating a covert subversion of Chinese oppression, we all here will cheer them on. And since you don't post any specifics, your point is unsupported. Nor would I think you would want to post that here, as the PRC does spy here.
But, your monetary contentions about higher pay should be supported by actual citations and references. Not wishful thinking.
There are very few US manufacturing companies in China. Even the big auto makers are only 50% foreign. There are some, like Boeing, and United Technologies (makes elevators etc via Otis) but even they are probably partially Chinese owned.
Largely though those guys are few and far in between.
The actual # exceeds 75% of our exports are not from US companies or manufacturing in China.
If you want to talk about the 25% we can do that...
