Sadly, it's part of so many American cities. Two come to mind for me. Hopefully, things have changed somewhat, as I visited both of these cities years ago. First is Augusta, Georgia, home of the Masters golf tournament, ostentatious homes surrounded by lush azaleas, and some extremely impoverished neighborhoods. The inequality is just so stark.
Second, Winston-Salem, North Carolina. I don't recall the name of the street, but it was right downtown, a very bustling, thriving commercial district full of restaurants, shops, and bars. Literally on the other side of the railroad tracks, same street, nothing but old, rundown houses. Sure, I understand that it's likely that section wasn't zoned for commercial development, but why was there *no* development? Not talking about gentrification, just some small sharing of the wealth. Wrong side of the tracks, indeed.
