One thing that is odd, is that as far as I can tell during the run-up to the referendum, no-one made the intellectual case for free movement of people to live and work throughout Europe. The 'Remain' camp made occasional and frankly incoherent statements about immigration while staying relentlessly on-message, sticking to the economy as the supposed winning hand. While of course the 'Leave' side played thoroughly on fear of immigration. Don't get me wrong, I'm sure it's economically efficient to have a borderless workforce, and there are also intellectual arguments about fairness. (I voted 'Remain', but that could be seen as self-interest for my own demographic). What isn't clear is why a lower-skilled worker already in a high-income country, who doesn't have any interest in moving abroad, wouldn't consider it in their own interest to pull the ladder up and restrict immigration.
