I slightly struggle with the statement, 'we don't need'. Firstly, for the majority of the people fleeing their homelands, they are in desperate need of help, whether it be food, education, freedom or healthcare. To shut your doors to people because YOU (by which I mean the UK) don't need them, seems a bit insular. Also, the public services are propped up and run by people from all over the world, so I find it slightly ironic that the very people who make the public services work, are also those who are blamed for public services being under strain. Secondly, what if, worse case scenario, there came a time when the UK desperately needed outside help, and needed people to do jobs others didn't want to do, or bring much needed skills that are lacking in the UK? By such a time, many of the skilled workers will have been snapped up by other European countries, and the UK won't be able to recruit people with the needed skills.
I understand I am probably slightly confused in my opinion. On the one hand, I am British, and proud of it. On the other hand, I've lived in France for nearly seven years now, and seen an efficient system of social care and an unbelievably high standard of health care. The response from French people I speak to is that they usually laugh as they blurt out...'ah oui...le Brexit.' Europe will continue without Britain, and Britain will continue without Europe, but when the day comes, as it inevitably will, that Britain needs some help from Her closest neighbours, don't expect open arms welcoming you back.
