Very interesting post, thanks.
One thing I would like to nitpick is the implication that factory jobs like Foxconn provide a "step up" or a way out. The fact is that most of these factory workers will never be allowed to integrate into the urban society, and in fact are legally barred from doing so. In China there really is such a thing as a "second class citizen": people from the rural areas are not allowed to settle in the cities on any permanent basis, and are denied most social services even while they are there. They are allowed to work in the factories but have to live in dormitories and generally can't take advantage of being in the city.
The only reason most of them are there is to earn money to support their impoverished families back home. The one part that does match up is that the eldest are often sent to work in order to pay for the education of the younger siblings --except that it's basic *elementary* education that has to be paid for (again, no social services for rural dwellers).
And this rural vs. urban classification is hereditary, so even if one of them manages to slip past the system somehow, they still can't change their enforced social class for themselves or their children.
