Lots to unpick. On your point about schengen: schengen does nothing to tourism (UK was not part of schenghen and the list of visa free countries for tourism is pretty much the same between Schenghen and the UK) or labour shortage (Schenghen isn’t about your right to work, EU citizens had the right to work in the UK even though the UK wasn’t in schenghen). And the point visa makes it pretty much trivial for well paid engineers to get a work visa in the UK. Where it makes it difficult is for low wage, low skill labour, which will create shortages, but I think that’s by design, whether you think it’s a good idea or not. I don’t think that tariffs would affect CPU much either, I understand it is mostly cars or agricultural products that are deeply affected. Not the least because you can see that the EU is importing most of its CPUs right now, doesn’t seem to be much of a barrier. I wouldn’t bet too much on the demographics helping remain in the long term. By conformism or risk aversion mostly there tends to always be a large mass behind the statu quo (which is why brexit winning was surprising). I think that will play both ways.
