Another thing is how commentators describe constituencies in psycho-graphic terms, not concrete interests. You hear that rural people are "unhappy and left behind." Well some rural people in England are that, and some work at the Nissan factory and they probably don't see Brexit as being good for their job. The point is that there aren't enough people working at an automobile plant (in England) to form a really powerful constituency. Society is more fragmented and there are fewer large blocks of people who have a concrete political interest.
