I think 'bring back control' is an ironic slogan from the Brexit campaign, since it seems unlikely to me that we can control many aspects of the economy. If you think of neo-liberalism, how much control of that is there? Of course, you can make attempts to reject it, but then there is the danger of becoming isolated, johnny-no-mates. Or there is the alternative of war, of course.
Anyway, it's going to be interesting to see if the UK can accept the free movement of goods, services and capital, but not people. I had to laugh at the slogan, 'we're open for business', with the rider, 'as long as you don't want to work/live here'.
