shaftoe, as a thought experiment consider why the neighborhood is run down. Did the people run down the neighborhood because that's what they like? How was the economic situation for these people? How were the schools, the hospitals, the law enforcement? Was there housing discrimination? How were their politicians? What was the funding like compared to other neighborhoods?
In other words, how was the neighborhood before it was crappy and how did it become so?
