That Europe, and especially the eurozone, has not been doing well since the 2008 crisis is beyond dispute. The single currency was supposed to bring prosperity and enhance European solidarity. It has done just the opposite, with depressions in some countries even greater than the Great Depression. To answer the question about what is to be done, one has to answer another: what went wrong. Some claim that policymakers made a set of mistakes — excessive austerity and poorly designed structural reforms. In other words, there is nothing wrong with the euro that could not be fixed by putting someone else in charge.
自2008年金融危機以來，歐洲——特別是歐元區——便一直沒有健康過，這是無可爭議的。單一貨幣原本應該帶來繁榮並鞏固歐洲團結。但結果正好相反，一些歐元區國家遭受的蕭條甚至比「經濟大蕭條」(Great Depression)時期更嚴重。要回答「該怎麼辦」這個問題，人們必須先回答另一個問題：哪裏出了問題？一些人聲稱政策制定者犯下了一系列錯誤——推行過度緊縮的政策和設計糟糕的結構性改革。換句話說，歐元沒什麼問題，換個人執掌就能解決問題。
