Re: Freedom of movement.
I'm tending towards supporting Brexit, but haven't decided. My anger over the appalling treatment of Greece and Cyprus, and belief in democracy are currently trumping the desire for an easy life. I still believe we'll vote to stay in, so hope it's a close vote or we might suffer political revenge for staying - which is a minor threat also if we leave. There are some things that annoy me about the EU, some that are good, and bits in between. But I'd say it's almost a nailed on certainty that little will change in the short-term, whichever way we vote. Unless common sense does break down, and everyone decides to start a trade war. There was a perfectly acceptable compromise deal to do on Greece (and particularly Cyprus), and yet Merkel's government, and others, chose to posture and grandstand and totally fuck over their economies, to no purpose.
I'd love us to have a free trade deal, with limited freedom of movement much more under our own control. And the EU to complete the single market in services (France, Germany and Italy in particular were much more eager to nail down free trade in goods, where we have a trade deficit with the EU, and have continually blocked/slowed freedom for services exports back to them from us). I'd also like to have seen some sort of associate membership for Turkey to tie them in as a democratic ally (looks too late for that now), and an end to the Common Agricultural and Fisheries Policies. Plus the EU to either get serious about a common security/diplomatic policy, or leave it to NATO. Sadly a bunch of those are mutually exclusive, and not all available if we leave, or if we stay.
Even if the rest of the EU were willing to grant us our fantasy, perfect deal, it'll take years. I read a piece on this that said the EU takes 4-10 years to negotiate a trade deal, the more complex the longer. And we're wanting something incredibly complex in a part of the EU that is still mostly done by unanimous voting - so if you don't get everyone on board, it gets vetoed. And there's going to be some natural resentment that we've buggered off, and that we're forcing hard negotiations on governments that they didn't want.
Additionally, the civil service have been more europhile than the politicians in every government except early Blair and Heath. And they're doing the negotiating.
So our choice is leave the EU without much of a trade deal, and suffer tariffs and discocation of trade while we slowly grind through sorting it out. Or do a deal where we do a quick and dirty shift from EU members to EFTA or EEA (there are technical differences which always confuse the hell out of me) - with the intent to slowly negotiate a few changes. Presumably once out of the EU we can discriminate on benefits against EU citizens, even though they get access to the country to work, which is a better balance than we have now. But while the Eurozone is so utterly fucked, we're going to get skilled migration from the EU, as well as unskilled, and short of deploying the army to the coasts and introducing ID cards, that's unstoppable anyway.
