On Marketplace this morning, commentator Will Wilkinson calls for a common North American labor market:
Mexico's GDP per capita is about what Poland's was in 2004. That was the year Poland became a part of the E.U., and started sending a large flow of newly-legal migrant workers to a much wealthier Britain. This neither increased British unemployment, nor overtaxed social services.
It's been a boon to both the British and the Polish economies, and a higher percentage of Polish workers now circulate back home. Romania and Bulgaria are even poorer than Mexico, but they are now set to integrate their labor markets with the rest of the E.U. in seven years.
