I do a load of work with farmers who, pre-Brexit, used to heavily rely on migrants from various Eastern European countries (veg packing, fruit picking, flower cropping). Many of those who came over have stayed and made a life for themselves (house, job for themselves and their other half, kids at a local school) all contributing to the local economy in the same way as those who were born here do. The balance came for the season, worked bloody hard and sent cash back home to make the lives of those who stayed in the home country better.
Since Brexit the solution has been to offer some seasonal visas (about 10% of the previous number) and to look to persuade local people to take the jobs...The problem is that the solution is no solution...the farmers want people to pick the crop (in large part the only way they get an income for their efforts for the previous year) whop actually want the work...they don`t want people doing the job badly and only because the job centre says they have to do it - those types typically last about a week before going off sick (it`s pretty hard graft) and the farmer has to start to retrain the staff all over again...It simply doesn`t work for them...
There were issues in terms of the local schools (some kids needed extra help as they didn`t speak much English) and GP`s (increased population made getting an appointment more tricky) etc but those issues weren`t caused by the people who came over - they were caused by a wholesale failure to properly plan - those who came over were paying their way (just as those of us born here do), the fact that the schools and the NHS are underfunded cannot be thrown at their door.
The solution that these farmers are reaching for is increased mechanisation so there will be significantly fewer jobs, a lower tax-take and virtually no-one taken off the dole queue. That worked well...
My thoughts at the time of the Brexit vote were
1.that there should not have been a referendum at all - the economics were too complex for mere mortals to understand; but
2. if we were to have one then you should not have been allowed to vote in it if you were old enough to have voted for the first one whereby we went in - you`d had your say - time for the next generation to make its own mind up...I think the outcome would have been very different...
