In Michigan the nice black city is Southfield. More upper middle class.
A lot of blacks Move to Atlanta.
There are also a lot of middle class neighborhoods around DC. Government jobs. They are Low crime. Of course DC has high crime neighborhoods too.
Upper-middle-class is likely to have less problems. Middle class, I dare somebody to post a city with a sizeable amount of blacks (50% or more) where crime isn't high or increased after they moved in. I don't know much about Atlanta, but from what I've been reading, that's turning into a shithole too.
Did you see that story out of Louisiana? Several black girls attacked a 15 year old black girl and stabbed her to death at a Walmart. The murderers were ages 12 to 14. Not only did they kill her, but live streamed it and bragged about killing her. When have you seen any white kids do something like that?
