My son lives in Brooklyn, I am so proud that somehow I produced a member of the “Gentry”, I’m sure that he will be as puzzled as I am to learn that moving to Brooklyn because it was cheap, made him a part of the high born.
It is cheaper than most of New York (I am told, never lived there). But people like your son have raised the cost of living in that area from what it was.
So the people who were living there are having to adapt to the changes, and don’t like it.
Chicago has areas like that, and it has been a source of tension to some of the groups.
