If countering inequality and promoting intergenerational opportunity introduces some marginal inefficiencies and blunts some incentives, it is more than worth the price. Public provision of critical basic services like education or health care may never be as efficient as private-sector alternatives; but where efficiency entails exclusion and inequality of opportunity, public provision is not a mistake.
这意味着收入再分配和确保基本服务的供给。即便遏制不平等性和促进跨国机会造成一些边际无效率、阻碍一些激励，这也是值得付出的代价。关键基本服务——如教育和医疗——的公共供给也许永远不如私人部门替代方案那样高效；但在高效率会造成排斥和机会不平等的领域，公共供给并不是错误。
