In St. Louis, the suburbs have actively petitioned against and succeeded in blocking light rail service from the city. They are convinced that somehow evil city dwellers (mostly black, let's be honest) are going to come out to rob everything they own. Only in the last few years did the rail service even extend to the near western suburbs near the fancy malls, which if St Louis wasn't gerrymandered to shreds, would probably be part of the city limits.
It turned out the nightmare scenario came to pass and lots of young, black, lower income residents from East St Louis started showing up to the mall. A strange thing happened though, instead of destroying the area, they mostly just brought a lot of money and purchased things.
Seems obvious to me, but rich white folks be crazy sometimes and mostly they write the checks when it comes to city planning.
