As though a veil has fallen from the common vision, the myths used to threaten, frighten and bully the peoples of Europe are standing as nakedly fatuous as the Colleagues. They still have their parrots - Will Hutton in the Observer at the weekend in a singularly crass piece for instance - but they are sounding increasingly ridiculous.
The EU prevents war in Europe: You need two things for war; militarisation, and young populations. Right now Europe is demilitarised, and our ageing population is just too old for war. If you want to know where the next big war is going to be, look to North Africa / Middle East. The US are moving all their assets to the Pacific. For the next few decades anyway, Europe is the most unlikely place for a large scale war.
A single currency reduces the cost of trans-national transactions: Probably true in the paper-instrument world of 1957, but absolutely false in 2012. Computers have reduced the frictional costs of currency exchange close to zero.
Without the EU, the UK wouldn't export anything to Europe: As we import marginally more from Europe than we export to it, any interference with trade barriers (or lack of) would hurt their economies more than ours; demand for London Dry Gin, Burberry handbags or JCBs remains the same. And we run a considerable trade surplus on services - which if the Eurozone cripples itself by the introduction of a financial transactions tax will grow.
Free trade areas must inevitably adopt a single currency: Tell that to NAFTA. Neither Canada nor Mexico see the need to change to USD.
The EU protects the Environment: Tell that to the UK's sustainable near-shore fishing fleet which has seen our fish grounds raped and despoiled by massive EU factory ships hoovering up every living thing including juveniles and breeding populations. Iceland, which regulates its own 200 mile fish zone, has full, healthy and sustainable stocks of Cod and other commercial fish and a healthy industry at full employment levels.
The EU protects jobs and employment: Sure. Unemployment levels in Spain of 25%, Greece of 23%, Portugal of 16% and so on demonstrate how good the EU is at maintaining employment. Moreover, the employment model in the EU is dividing into permanent, older, workers with high levels of reward and protection (and high cost) and insecure younger workers on part-time or short-term contracts on pay terms that get around minimum pay costs. Without the EU's interference in the Employment field, it would be fairer to all and help national competitiveness.
