it actually costs more to produce goods in china than it does in the US
the reason is that if an item costs $18 to make in the states, the same product costs $20 to make in china (i.e. it costs $12 to manufacture the product and $8 to ship it)
china may have already gone bankrupt because it was unable to silence the US and european industry. Sorry Mr. Chinaman, but we outlasted you, and now you have to pay up.
so the US government cannot take a moral high ground as they think they are doing, because, by not being tough with china, they are actually screwing up the chinese people
what china is doing to its people is making them artificially poor with its currency policy, so either the people cannot save up, or they cannot spend (unless of course they are a party to the communist system)
so if the yuan appreciates, the chinese people can save more, and if they don't want to spend their capital, then china can pay the US back with the money in the chinese banks
so then the US government can make even more money by charging tax on more exported goods and the US companies can be more competitive because of the higher volume of goods produced
