It is no accident, for example, that Europe’s most successful welfare states were created in ethnically homogeneous Scandinavia. People in those countries had the sense that they could understand their neighbors and fellow citizens, and that they shared a close link with them.
这种共同身份定义的最佳范例就是种族相对单一的斯堪的纳维亚半岛，欧洲最成功的福利国家都集中于此。那些国家的人民都认为自己可以理解邻居和其他市民的思维方式，彼此之间都享有非常紧密的联系。
