Sadly, this is why the vertical ghettoes were built in the first place. They take up less taxable land and use fewer city resorurces.
Actually, the worst of them (the Robert Taylor projects) were built on the east side of the Dan Ryan Expressway in an effort to keep the ghetto from spreading to the west side of it (which, coincidently, included the neighborhood where the elder Mayor Daley lived and grew up).
Didn’t work.
