Removing restrictions on immigration aren't a silver bullet. The opening of labor markets in the EU has caused much lower social mobility than previously expected (ie. many Greeks stayed in Greece even though they could get much better jobs in Germany).

Is there anything I can read up on this? I hear the population of Baltics halved, sounds like a rather drastic effect.

Although I didn't imply immigration restrictions are the only problem either- indeed the language and other cultural barriers as well as our tendency to form bonds that are painful to break all work against mobility.
