"much of our affluence is based on manufacturing in China"
yes it is a real problem. It's skewing the prices of goods in America, and inflates our materialistic, greedy nature. If prices reflected the cost of resources and human labor that go into a product, we would be much more mindful of our purchases. This is only a short-sighted, short term gain.
There is nothing normal about how many hours an American works for e.g. an iPhone, vs a person from another [almost any pick] country.
