To help real refugees, be firm with economic migrants | Nick Cohen | Opinion | The Guardian

I get the feeling that this column is (as often in immigration matters) fine in theory, yet useless about how the theory is to be applied in practice.   Especially as far as Europe is concerned.

If countries with land bridges to economic basket cases had a simple way to stop unwanted entry, or returning those who have arrived, they would have worked it out long ago.  Take the United States and Mexico, for example.
