The Post today has an article about foreclosed homes in the suburb attracting homeless, teenage kids, and crime. In other words, attracting the sort of thing that abandoned buildings in the CITY bring in.
The suburbs could well be the new slums. A recent Atlantic article covered it in more detail. It isn't just foreclosures that are making people abandon these distant suburbs. It is also a change in preferences, and a growing desire for homes where you can walk to shops and restaurants, instead of having to drive to the end of your driveway just to pick up the newspaper...
So don't be surprised if the suburban blight should grow greater.
