> I'm trying to think of a single metric by which the EU hasn't been a massive success.

- Number pages of lunatic regulations

- Money gone into the EU

- Not a metric, but fitting very different philosophies of how to handle the domestic currency under one umbrella (ECU, Euro) has lead to massive tensions between the involved countries and their populations in particular when the Euro crisis hiy (e.g. in German "Pleitegriechen" [bust Greeks], PIIGS (pigs) countries (Portugal, Italy, Ireland, Greece, Spain)). If there wasn't a common currency, each country would have solved this problem on its own terms. Now there is hate that continues up to today, and these countries (including their citizens!) can be used as scapegoats.
