You do not take into account the social dimension of the change in China itself. The one-child family has produced over some 40 years a highly educated youth that is taking over the industry but one of these at least college educated young people replaces three or four low-trained workers. The Chinese industry is shifting from a labor industry to a high tech industry, the only way one person can replace three or four. That is also one motivation why they are reducing pure labor industries like coal mining and yet at the same time making them high tech. They will soon enough have no low-qualified and low-trained workers anymore, or so little and aging and they will be provided with simple jobs as I saw last year in Chengdu.
