someone in Cambridge who reaps the benefits of world class collaboration with colleagues from around the world.
And that collaboration may well produce drugs which save people's lives, or new medical treatments, or new technologies which benefit all of Society, not just the scientist in Cambridge.
Today the Sun ran a headline complaining that most EU immigrants can't be "booted out" when we leave the EU. Walking past a university colleague from the EU who saves children's lives every day, I felt ashamed that he had to see such a headline before going into surgery for a child whose parents may well want him "booted out". A significant fraction of our world leading research doctors in university hospitals are not British.
People on this thread want Remain voters to acknowledge that those who voted Leave for immigration had legitimate concerns. (Even Leave voters in areas where there are almost no immigrants and shortages in services and housing are caused by other reasons.) Ok, fair enough.
But those who voted Leave for immigration reasons should also acknowledge that relatively unrestricted movement of scientists and doctors in and out of our country, all around the world, is responsible for a huge amount of scientific, technological, medical and pharmaceutical progress. If you shut off such immigration (and indeed emigration) entirely, we would fall behind in these areas and this will affect everyone in Society.
People talk about points systems and controlled immigration but the current system for non-EU visas is complicated, expensive, time-consuming and generally set up to deter even the "exceptional talents" (Tier 1) and "highly skilled" (Tier 2) from coming. I think the UK should think very seriously about whether making such people (non-EU and EU after we leave) so unwelcome is actually in the best interests of anybody in this country.
