States are right to spend generously on education; but, of the world’s top ten universities listed by the Shanghai ranking, seven are private. Successful pension systems often have a solidarity pillar (public) and a contributory pillar (private).
教育、退休金或穷人的住房也是如此。国家在教育上慷慨投入是正确的；但是，在上海大学排行榜上，前十名中有七家是私立大学。成功的退休金制度需要团结（公共）和出资（私人）双管齐下。如此等等。对现代公共政策的学生来说，这些都是老生常谈。但科尔宾主义者似乎完全不得要领。
