Totally agree with this perspective. The deal we had - in the single market but not the Euro - gave us most of the upside and little of the downside. Soros is on record saying the same. The bullying of Greece by shutting down their banking system, and the special treatment given to French and German banks that had foolishly loaded up on Greek govt bonds was execrable. I prefer Brexit to Eurozone membership. But the Euro opt outs that the UK and Denmark have are the best option.
