What about the countries they are coming from and their economies. What is the end game, should Europeans be shipped off round the world so the power of diversity can work its magic. That sounds more like colonialism. And should China and India do the same?
Well, here’s some stuff to think about.
1) Many people come from poorer countries to richer ones, work for a bit, gain skills then take them home again. Of course many stay, but let’s not ignore the fact that there is at least some two way traffic.
2) It’s not just people that move, it’s also goods and services, they are bundled up together in the EU at least. So if you need the expertise of a company in another EU country, you just call them up and there’s no issue. There’s no restrictions and no hoops to jump though. (In my job we end up sitting at a client’s computer telling them what to do – we aren’t allowed to actually do anything, unless we’re in the EU where we get full access.) This is skills transfer in the opposite direction.
Do you really think the poorer EU countries would have been better off without the free movement of people, goods and labour?
