Europe may never be an “optimum” currency area by any standard. But, without further profound political and economic integration – which may not end up including all current eurozone members – the euro may not make it even to the end of this decade.
欧洲也许从来都不是一个“最优”货币区，不管从什么角度看都是如此。但是，如果没有更加深远的政治和经济一体化——也许最终无法将所有当前欧元区成员国纳入进来——可能连这个十年都撑不过。
