Just a thought experiment. Imagine a world, where everyone can move anywhere in the world. What do you think it would happen ? Don't you think, that people in less prosperous countries would move to more richer countries. And what would that lead to, do you think people from richer countries wouldn't feel the hard impact on their economy ? My point is this. In the USA, there are less cultural and economic differences between the states, so there won't be as many mass immigrations from one state to another. Now think about if USA decided over night, that it would open it's southern borders to all of South America, I think we all know what would happen. And the same thing could happen in EU, because you get to huge cultural and economic differences on the borders of EU. Just think about Turkey and negotiations (their demands) to become part of EU. That would be a total disaster. What good is EU or USA, if it can't keep ILLEGAL immigrants away ?
