Normally ai would agree with you but in this case, those areas in St Pete, and other places in Florida and around the South were established as black communities. Pinellas county was very agricultural at one point, lots of orange groves and cattle ranchers (who were the real Crackers, a name that is now a slur). A lot of shipping and rail came through. Big hotels like The Vinoy and The Detroit were built, and all these industries needed workers. Black people were historically in agriculture, labor, and service before the elites told them those jobs were beneath them...which displaced them and led to our current state with increased crime, violence, etc.
