Thanks for the interesting story of how migration can be deemed a success. It seems to run contrary to what we often see with regards to migration--laborers working for miniature wages abroad, subject to human rights abuses and ostracized from society. I'm wondering if instances like this are more prone to succeed because it seems to be intra-country migration. Although China possesses a multitude of people and cultures etc, it would seem that these migrants are aided by their ability to speak the language and assimilate culturally. This would seem to increase their chances of prospering and allow for a much smoother transition to life in the urban centers.
