The Future of Suburban Living

As the top 20% crowd into the cities, voluntarily as that is where all the good stuff is within walking distance including most of the jobs that support the top 20% what happens to the suburbs that they leave?  Property values crater, and it becomes reasonable for the bottom 80% to achieve the American Dream of suburban living.  Rents in the strip malls and local shopping centers crater along with the property values, and become affordable for bodegas, Dollar stores, and other services catering to the lower income groups.  Assuming existing transit is maintained, (roads don't matter) as travel outside the neighborhood is mainly for jobs serving the 20%.  The 20% will insure it is maintained as they don't use it anyway and they need the service people who are gentrified out of the city.  

The current suburban standard of 4-5 bedrooms and 2-3 baths will serve an extended family of many as well as it serves the current family of 3.  The family room or a big downstairs room will be turned into a dorm for the kids and the adults will occupy the 4-5 bedrooms.  The modern luxury kitchen will easily serve dozens as well or better than it serves 3.

One can expect the current suburban developments to become ethnic enclaves, since once the block is busted and prices crater further, friends and families will join the blockbuster and remake the development to serve their needs.  The fences will come down and the large backyards will connect to be a big playground for the neighborhood.

It is happening as we chat, many suburban neighborhoods and cities connected by transit to the urban core are now ethnic enclaves, and the white homeowners are taking the money and running while the money is still there.  The elderly to "Adult communities" and the working ethnics are blockbusting a new community for their ethnic group.
