Until a couple of years ago, Eurocrats liked to boast of two great achievements: the euro and the border-free area. It is now clear that both were fair-weather schemes. The debt crisis cruelly exposed the weaknesses of the single currency, and the migration crisis brought Schengen to the point of collapse. Yet the EU’s response, in both cases, was to treat deeper union as an end in itself. The euro must be held together, even if millions were thereby condemned to poverty and emigration. The Schengen Zone had to be salvaged, however many illegal migrants were attracted to Europe in consequence.
