I am willing to bet just about everything I own that if the same number of unskilled French or German workers (who have a similar wage standard as us and are therefore unlikely to move here in large numbers) had arrived in the last decade as have eastern europeans they would of been met with the same concern. I seem to recall that you have mentioned on this thread some time ago that your partner works in the NHS, she does not therefore qualify as unskilled. Quite the opposite in fact, she is an asset to UK. You seem to of fallen into the trap of believing the verbal diarrhoea that spills from the BBC and other national news outlets. Controlled Immigration itself was never the issue, if your referring to the freedom of movement act (aka complete chaos) then yes ill grant you it was a major point but it really needn't of been. The issue was and still is the free and uncontrolled movement of large numbers of unskilled workers who jeopardize large numbers of unskilled British workers. If we lived in a utopia were every country had the same standard of wage and living conditions perhaps it would be workable but sadly we don't and I don't believe it's truly workable anyway. Do you really think the EU permits free movement because it cares about its people? You don't think it's the worst type of capitalist who only permits people to go wherever they want because it means cheaper Labour for their corporate friends?
I find it quite sad if any of your friends have been told to "go home" or received abuse of any kind. Myself and many of my friends (those of us who told people how we have voted at any rate) have received much abuse and in the case of one of my friends actual physical threat's. These animals are on both sides of the vote but I'm happy to say they are in reality a small number.
On the contrary, I've actually read numerous studies that aim to provide data to this issue rather than relying on anecdotes. The data says that migrants contribute more than they consume, they are better qualified than the native population, and their children do better than the native white population at school. What's more, EU migrants also tend to do better than non-EU migrants, who the government have the ability to control movement of.
Sadly, in Czech (and Hungary, Slovakia and Austria) there are attempts to use Brexit to puff up the anti-Muslim hysteria in the country. The sad irony is that they use much the same rhetoric that was used by certain tabloids and politicians here when free movement was expanded to those countries.
