Migration has once again become a touchy political issue

The Economist:

UNTIL recently, politicians who inveighed against immigration could expect support from an angry minority of voters in many Western countries. Some, like Australia’s Pauline Hanson, won moments in the limelight and then faded away. Others got closer to political power: in France in 2002 the anti-immigrant Jean-Marie Le Pen reached the run-off stage of the presidential election; Denmark’s centre-right government has been kept in office with support from an anti-migrant party; and in Austria in 2000 Jörg Haider’s far-right party joined a coalition government. On each occasion this was controversial, but could be explained as a quirk of the electoral system, not a reflection of widespread anti-migrant sentiment.
Today, however, hostility to immigration is becoming mainstream. Britain’s prime minister, Gordon Brown, whose Labour government has allowed remarkably high rates of immigration for years, recently called for “British jobs for British workers”, a meaningless slogan previously used by the far-right National Front. The opposition Conservatives’ leader, David Cameron, says he wants to see “substantially lower” immigration. Both government and opposition say they will keep out workers from Bulgaria and Romania, along with those from any other new EU members, for as long as possible.
