The Chinese are dependent on your consumption but they earn U.S. dollars from it. Some scholars argue that with these immense sums they buy U.S. treasury bonds and they possess so many of them that the Americans are paying the interests  through their taxes. And the economy is implicitly dependent on foreign owners of bonds. So you are right about the American dependency on countries with low-paid labor and cheap products.
