The immigrants do want to work, but find themselves stuck outside a heavily-regulated jobs market that could have been designed by a populist demagogue to keep them out. For unskilled work in restaurants, for example, the trade unions’ unofficial (but strictly enforced) minimum wage is about £10 an hour. For unskilled immigrants, especially from countries like Afghanistan and Somalia with no properly functioning education system, this means the Swedish dream ends before it begins. A policy intended to lift everyone’s wages has ended up destroying entry-level jobs, and ensuring thousands of immigrants are shut out of the economy, denied the first rung on the ladder to work.

Among Swedes, unemployment is about 4 per cent and falling. Among immigrants, it’s 22 per cent. No developed country has a higher differential: in Britain, there’s barely any difference at all. The Swedish government describes itself as a “humanitarian superpower” and accepted refugees on that basis, but its fatal mistake was failure to welcome so many without being able to integrate them. Hence the zones of joblessness and the criminality, and the inability to know what to do about it.

The resulting shadow society is now quite advanced, with its own moral codes and even its own legal system. Tribal courts are now in operation, dealing with crimes – or, at least, what count as crimes in the underworld. The fine for a failed attempted murder is about £50,000, according to Malmö’s chief prosecutor. Of the 37 murders and attempted murders in the first half of last year, just seven have been solved. But what are police to do, when witnesses drop out and victims drop the charges? Officers admit that, when child refugees go missing from care homes – feared to have been passed into prostitution or criminal gangs – there is not much they can do.
