That's exactly the point. All those politicians protesting and being concerned, where were (are) they when production went to China?
Nobody protested then, but now on a "safe" subject (not being economic) now they have "concerns" I can't take that serious. It would have much more impact if people at least would try not to buy "made in China" stuff or if goverments would try to prevent industry moving over there, but that would cost, so ... everybody sticks to idle words.
( Don't get me wrong, I do take the human rights isues everywhere very serious though).
