Denmark’s left defied the consensus on migration. Has it worked?

Venturing beyond the ring road of just about any western European capital, far from its museums and ministries, often means encountering a landscape that mainstream politicians prefer to gloss over. Many suburbs are havens of familial peace. But others are the opposite: run-down dumping grounds into which societies shunt the immigrants whom they have failed to integrate. In the unloveliest banlieues surrounding Paris, Berlin or Brussels, criminality—whether petty, organised or drug-related—is often rife. Social indicators on education or employment are among the nation’s worst. Ambitious youngsters looking to “get out” know better than to put their real home address on their CVs.
