Legal immigrants, but illegal workers / Economist, 4 April 2007

"THERE are economic reasons to deplore the decision by so many rich European Union countries to close their labour markets to citizens of Bulgaria and Romania, even after those two countries joined the EU as full members at the start of 2007. Bear in mind that, as citizens of the EU, Bulgarians and Romanians have the legal right to enter any other EU nation without a visa, and to remain there for three months at least. You did not have to be a psychic to predict that if rich nations opened their borders to citizens from much poorer neighbouring states but banned them from legal work, the most likely effect would be a rapid expansion of their local black economies."
