We have a nice black family in our neighborhood who isn't in the least bit shy about letting people know that they moved here precisely because our working class neighborhood has less black people.
Funny, how that works, isn't it?
I think it was in one of Thomas Sowell’s books where he related how middle class blacks moved as poorer blacks moved in from down south. It really isn’t rocket science. We all want to live in areas where the local ‘culture’ appeals to our way of life.
