To be sure, some workers in Europe do migrate. In the absence of the high degree of mobility seen in the US, however, overall unemployment can be lowered only if high-unemployment countries can ease monetary policy, an option precluded by the single currency.
虽然某些欧洲劳动者确实能在各国间迁徙，但由于缺乏美国劳动者所拥有的高度流动性，欧洲的总体失业率只有在高失业率国家实行宽松货币政策之后才能有所下降，但这条路已经被单一货币堵死了。
