The low cost of manufacture in China is not due only to low wages. Their factories are all new, and equipped with the latest automated tools, such as the machines that "stuff" circuit boards with all the resistors, capacitors, and ICs, and wave solder the result. This resembles the situation in Europe following WW2, when we rebuilt all their factories which we had bombed to rubble, while we continued to use our 1930's facilities.
Also, people who decry the balance-of-trade situation overlook the fact that much of what we import is our own product being made in China.
