I've heard that in "the south" they don't care how close you get when you don't get too rich, but in the north they don't care how rich you get when you don't get too close.
assuming some baseline animosity against a group of people (the "outgroup"), in the south the outgroup are resented for being successful, but if they can just be perceived as lesser the main group doesn't mind having them around. whereas in the north the main group doesn't want the outgroup mingling with them, but as long as they keep to themselves they can be as successful as they like.
