Those who violate the rules must be warned and finally sanctioned – preferably in an automatic fashion. Those who violate the rules consistently, and even announce that they will continue in their misbehavior, should not be allowed to blackmail the community and should ultimately consider leaving the club.
可以把欧元区比作会员俱乐部。除非会员们尊重有他们自己制定的规则，否则俱乐部就难以为继。违反规则的成员必须得到警告，最终得到制裁——这一切最好自动发生。决不能允许不断违反规则、甚至宣布对不当行为死不悔改的会员要挟俱乐部，应该考虑把他请出俱乐部。
