The process is fraught with challenges. At the beginning of the process, what these countries have to sell to their customers is their relative poverty. Their poverty allows them to sell labor cheaply. If the process works and the workers are disciplined, investment pours in to take advantage of the opportunities. Like the investors, local entrepreneurs prosper, but they do so at the expense of the workers, whose lives are hard and brutal.
It's not just their work; it's their way of life. As workers move to factories, the social fabric is torn apart. But that rending of life opens the door for a mobile workforce able to take advantage of new opportunities. Traditional life disappears; in its place stand the efficiencies of capitalism. Yet still the workers come, knowing that as bad as their lot is, it is better than it once was. American immigration was built on this knowledge. The workers bought their willingness to work for long hours and low wages. They knew that life was hard but better than it had been at home, and they harbored hopes for their children and with some luck, for themselves....
As the process matures, low wages rise -- producing simple products for the world market is not as profitable as producing more sophisticated products -- and the rate of growth slows down in favor of more predictable profits from more complex goods and services. All nations undergo this process, and China is no exception. This is always a dangerous time for a country. Japan handled it well. China has more complex challenges.
