As I was walking down my road the other day, I estimated that probably 80% of the shops and services are run by non British Europeans. If they all had to up and leave it would have a devastating effect on the community as a whole. Can you own a business in the country you are being deported from? Or would you have to sell up? Even if you can keep it you now need to find workers and as previously mentioned GENERALLY brits don't want to work 10+ hour shifts in a corner shop. Or at weekends (and I myself fall into this group - have done it, don't want to do it again). This is part of the reason I'm in. Where I live is a much nicer place because of all the different cultural backgrounds. We have a Greek Deli and a Polish Shop and an Italian Deli (all run by their respective nationalities) and a couple of (delightfully) crazy Greek restaurants and an amazing all day breakfast cafe (run by non british Europeans) and a british run bar/restaurant. Also run by non british europeans, hairdressers, beauty salon, barbers, tailors... oh and a gym. I always forget the gym....
