Third world countries artificially suppress wages in order to attract capital. It's good for the Chinese government, as they get more revenue and large GDP growth. It's good for western governments and their citizenry, as they get cheap goods. The only losers are the billions of people who are forced to work essentially as slaves.
It is truly ridiculous to try and pass this sort of international trade as part of the free market. In order for that to be the case, both the US and China would have to be free themselves - which is obviously insane.
