Just to be clear, we are talking about investing in China to take advantage of cheap labor and cheap imports, right? Both must exist for a corporation to find an advantage. We still have cheap imports from Mexico, just not so cheap labor anymore.
Yes we are. But, if you mean cheap exports FROM China, which are then imports INTO your own country, then cheap "imports" and cheap labor are practically the same thing. The import is cheap precisely because it was manufactured with cheap labor. Mexico doesn't have cheap labor any more. Try to find something that says "Made in Mexico." You'll have a lot of trouble, and if you do, it won't be something cheap.
We used to do the same with Korea and Japan. Again, this may be a good opportunity for opportunists to take advantage of China, but I have a feeling that China will not react the same way as Korea and Japan. In fact they are building their factories in specialized zones. This way they get trained labor forces that are geographically based. It is an ideal way to plan for possible nationalization of these factories. So go ahead and use China as a gleaming example of unrestricted capitalism via no-minimum-wage. Time will tell. I am still skeptical. I will classify using China to make you argument as special pleading.
Time
has told. China (and India) is an example of unrestricted capitalism when it comes to wages, and
has shown that, when companies have to compete for employees, wages do go up, and working conditions do improve, even without minimum wage laws. Whatever the government decides to do later is irrelevant, because it would not be unrestricted capitalism, and it will have nothing to do with the point of "free market competition for wages in an environment free of minimum-wage laws DO in fact increase wages, improve working conditions, and decrease unemployment." (And Mexico, and to a lesser extent Kenya, and Korea, and Vietnam, and South-Pacific island nations).
