I have properties in gentrifying neighborhoods located near ghettos.
I remember the first thing I noticed when driving through a ghetto early in the morning; it was the lack of rush hour. Furthermore, most of the early-morning drivers were women.
It seems that the ghetto society has decided that women are supposed to work and go to church, while men are supposed to play and commit crimes.
I know that's a generalization, but that's the impression that an outsider will get if he has to live or work in a ghetto temporarily.
[Full disclosure. Those generalities only apply to California and Florida, where I've lived most of my life. In constrast, during my visits to Georgia, I've noticed many black middle-class men who were well educated, soft spoken, and hard working.]
Your observation is really not a generalization.
Come to Richmond Virginia, and you'll find your observations VERY accurate.
