That isn't some coincidence. The biggest beneficiary of the Eurozone relies on the suffering of its less successful members and this is ultimately reflected by the fact that poorer countries in the Eurozone don't catch up with the rest of the EU and in fact the opposite happens. Meanwhile for EU countries outside the Eurozone it is smooth sailing because they don't have to suffer for the benefit of a country that is role playing as the hero of the Eurozone.
