The Ukip posters will offend more Londoners than eastern Europeans

Globalisation is like a rising tide; we’re all living in our separate ponds with their own little social ecosystems until the floodwater starts to rise and turns them into one big lake. Many fish, especially, the big ones, are going to benefit but many will suffer in this frightening new world. It is that fear which Ukip’s new posters are aimed at addressing (or exploiting, depending on your view).

Sure, Europe is about free movement of labour, but that movement is highly imbalanced and has been for a number of years. Far more people are seeking to come from southern and eastern Europe to work in Britain than vice versa, and therefore that puts pressure on some British workers (let alone the question of infrastructure). If British plumbers and builders were moving to Poland or Lithuania in equal numbers then, yes, free movement would be beneficial to all. That is not the case.
