The only consolation is that when (not "if") Britain becomes the world's newest banana republic with a failed economy and total social breakdown (think Haiti), the grass may well be greener in Eritrea, Syria, Afghanistan et al and the economic migrants may want to return to their tribal homelands, or find a country safer and wealthier than Britan - maybe somewhere like Ukraine or Moldova. There may well be a fortune to be made selling rubber boats and lifejackets to them on Britain's southern shores. That will be short-lived however, because the French will disincentivise them by simply blowing them out of the water.
