The Indian and Pakistani diasporas continue to grow, as they rarely marry people from this country, preferring , via arranged marriages via family or tribal connections, to bring in a spouse from their historic country. This is not a pejorative point but the government has done little to deter this habit. Even in recent years non EU migration has been about 1/2 of the total. My point is that we seem unwilling, or unable to control migration and this would not change if we voted "Out". Do the "Out" camp seriously believe that British youngsters would take on jobs such as potato or cabbage picking? I saw a trial on TV where they proved unable to cope. Nursing still relies on , for example Philippine people, indeed my wife recalls back in the '60's many of her nursing cohort were from other countries, so I see no sign of change there. There may well be arguments on legal or economic matters but I have little faith that immigration would change much.
