This is not to say that a single economic policy should be imposed on everyone; but Europe does need a higher degree of coordination and convergence to ensure that everyone is at least heading in the same direction. Like cars on a highway, some may drive more slowly than others, but there are minimum and maximum speeds and all must go with the flow of traffic.
当然，笔者并非要求各成员国都执行同一经济政策。但欧洲确实需要更高度的协调与聚合以确保各国至少都向着同一方向努力。这就好比是高速公路上的车，有些人开得比别人慢，但路上的最高和最低限速使得所有车辆都有序前进。
