Moving to Shanghai? You Need a Certain Document

      That document is a piece of paper, actually a diploma.  To become a resident of this big Chinese city, famous for its cosmopolitan atmosphere and coast wise setting, you must be part of the ducated class: those Chinese who are privileged to have been given a slot at a university, a place not universally available to all citizens.  Maybe it's a demographic/population control issue.  Too many people make any city uncomfortable.  Shanghai, with its 12 millions +, might have problems if the government practiced the open door policy allowing any citizen with a will to move and live there, they'd end up like Rio De Janiero with vast shanty towns(favelas) that house hundreds of thousands of poor citizens and lack basic services such as sewer and water service.   Shanghai does not want to end up like this example.  Even Hong Kong has cleaned up the live aboard bay dwellers that have existed in the harbor for centuries.  Maybe we could learn something from this policy: limit the free movement of citizens until a given location can handle the increase in population numbers.
     Ok, you want to move to NY CIty and get a job.  Hmmmmm.  No, not enough space.  We'll put you on the waiting list.  Likewise, San Francisco, San Jose, Los Angeles, San Diego, Chicago, Dallas, Denver, Fresno, Bakersfield, Reno, Las Vegas, Seattle, Atlanta, Washington, D.C., Philadelphia, and on and on.  Planners would sign on, maybe McDonalds would not.   More documents needed.
Not.
