In the UK, you can go check litterally any hospital / care home / hospice. A vast percentage of doctors nurses and care assistant are not British. Without them we would not have a health service. Going out, check in hospitality and restaurant (waiters, cooks, hotel staff) , in the UK a vast majority are non British. The crazy thing about the UK is that with brexit, should we get rid of foreigners, we would have no one to do these jobs. In agriculture, fruits and veg pickers are mostly foreigners as well. The UK cannot be a successful economy without immigrant. plain and simple. The sad thing for me is that many do not see it and when they do, it ll be too late.
