The recent economic success of Spain has not received the attention it deserves. One element in Spain’s resurgence, which I didn’t previously know about, is a relatively liberal immigration policy. According to BusinessWeek:

Over the past decade, the traditionally homogeneous country has become a sort of open-door laboratory on immigration. Spain has absorbed more than 3 million foreigners from places as diverse as Romania, Morocco, and South America. More than 11% of the country’s 44 million residents are now foreign-born, one of the highest proportions in Europe. With hundreds of thousands more arriving each year, Spain could soon reach the U.S. rate of 12.9%.

And it doesn’t seem to have hurt much. Spain is Europe’s best-performing major economy, with growth averaging 3.1% over the past five years. Since 2002, the country has created half the new jobs in the euro zone. Unemployment has plummeted from more than 20% in the 1990s to 8.6%, within shooting distance of the 7.2% euro zone average. The government attributes more than half this stellar performance to immigration. “We are very thankful for all these people who have come here to work with us,” says Javier Vallés, economic policy chief for Prime Minister José Luis Zapatero.

Apparently all those immigrants haven’t “taken all the jobs.” Ask your favorite Lou Dobbs-loving friend to explain to you how this is possible.
