It's not so much that I think it will automatically help them as much as I think that it's unfair that we restrict people's ability to improve their lot in life because of their nationality. Moving from one place to another should be their decision, just like a citizen from a poor city can decide to move to a richer city in the same country (or if you wish, a citizen from a poor EU state can move to a rich EU state - same reason why I fully supported poorer countries like Bulgaria, Romania & Croatia joining the EU & hope to see Turkey joining as well at some point in the future). Not granting them that freedom reduces class mobility, even thought it's not the only element in the equation. We should definitely additionally also try to fix the other factors reducing or limiting class mobility.
