I think everyone's over thinking this. 5 years ago I never heard anyone,ever, discuss membership of the EU. Some people went to Europe on holiday, some people moved there for a bit of sun. Some people worked there. Some people had their plumbing done at a reasonable rate. Most people had never been there or to London or Southampton. Then, a few people, who had enough money, thought they could make some more (or were afraid they might lose some) and manipulated the above and succeeded. Now us plebs are arguing whilst they are smurking.
