This is the end result of the “global city,” something discussed at length in Richard Longworth’s Caught in the Middle: http://www.goodreads.com/book/show/1961681.Caught_in_the_Middle
Longworth explained that this is how things are going in other “global cities” as well. A privileged elite at the top with a vast underclass at the bottom. If you want to stop this, said Longworth, you must also want to stop globalization.
How to prevent this? If you have the answer, said Hinz, you should run for mayor. Anyone?
