Members from UK, I advice you to vote yes to stay in EU. You will only lose by leaving. Because you will not really leave.
I will admit I'm worried for my stocks ok, but no good for UK to leave that's sure.
That means goods, services and labor flow freely between UK and the EU. In return, however, UK has to adopt a large number of EU laws without having a formal say in how they are shaped. UK also will have to pay about the same amount of money into the EU budget on a per capita basis as before, a think tank that has declared itself neutral in the debate.
