There's the problem, NJ. Up here in Cambridgeshire, the workers in the fields and in packing plants, right up to fork-lift truck drivers, all come from other EU countries. When local TV asked unemployed local young men, all fit, whether they'd like jobs at well above the minmum wage (these workers were on such rates) , they all said 'yes' until they found out what the jobs were.One of them, crushingly and without a trace of irony,, said it would mean working with foreigners.
I suppose you have an answer, do you, as to who is paying for these British men, and their unemployed partners and their children, and will in future, come to that? Seems to me that the foreigners are, as are the rest of us.
