Two, upper middle class still don't get it. They're still tone deaf. The Brexit was the working class demanding what was promised them, which was prosperity that never came. Instead they got sold out for a cheaper European work force (not faulting the Poles for wanting better, if just is) while the middle upper classes (professional class) got to enjoy the spoils and got to snicker at the working class for being upended by outsiders.
The professional class are now complaining that they will lose their privileged position... A position the working class never got to taste. So, there it is, they called in the promise and foolish or not, they at least are doing it by their own hands rather than that of the tone deaf professional class who never cared for the working class.
Of course, the professional class, showing their class in style, as they are wont to do, go about castigating the working class by telling them how provincial and selfish they are... But just look who is complaining about losing their privileged status.
