My grandparents used to tell me about a neighborhood on the north side of Lansing, where all the houses were built by auto workers in the 1910s and 1920s. They said that everything was fine until the local "Ma & Pa" stores kept getting burglarized and robbed. The owners were forced to close shop and relocate, leaving no places for the locals to buy essentials. Then the locals started moving away, leaving behind a lot of empty buildings and families too poor to move. If it had not been for the Michigan School for the Blind moving in, the area would still be a blighted slum. As it is, gentrification did not start to take hold until the mid-1990s.
When entertainment and retail establishments move out, there is no incentive for people to stick around or move in. This is what I expect to happen in places where the smaller retail stores were looted and burned.
