It was in a hotel bar in Salzburg on Wednesday night of all places where I got chatting to a couple of lads from Walthamstow. Their company fleeces and work trousers indicated they were there on business rather than to endure the ubiquitous Mozart schmaltz that has polluted this otherwise attractive 17th century town. They were service engineers - skilled technicians who flew around Europe staying in 3-star hotels and maintaining bits of building kit. They were quite at home amongst the Turkish cab drivers, Halal fast food joints and Roma beggars on the footways. Their iPhones - frequently accessed - kept them anchored in Walthamstow. As a lesson in labour mobility, it was admirable. Austrian labour protectionism, which I imagine insists that a photocopier technician has served a seven-year apprenticeship and is a paid-up member of the Kopiererwartungverband before they are allowed to clear a paper jam, has had to give way to the free market - in this case Walthamstow workers who can read Japanese service manuals written in cod-English.
I must say I'm actually in agreement with Cameron's opponents in Europe who argue that free movement of workers is inviolable. Brits are actually well-suited to take advantage of these economic freedoms. The problem isn't free movement of (European) workers, it's that welfare rules, particularly in the UK, haven't caught up with the new reality. Hence we pay millions in child benefit to kids in Poland and English dole to idle Slovakian alcoholics in Slough.
It's African and Pakistani immigration rather than European workers that have caused real damage to England. UKIP is just scared to say so.
