从威廉•朱利叶斯•威尔逊（William Julius Wilson）到查尔斯•默里（Charles Murray）等社会评论员都认为，将人们越来越多地划分为内部同质的“社区、学校和婚姻”，正在刺激长期的不平等。对一个正式模型的评估表明，这些担忧是多余的。为了使教育的稳态标准差增加1%，邻居之间的教育相关性必须增加一倍，或者配偶之间的教育相关性必须增加三分之一。事实上，在过去的几十年里，这两种相关性都略有下降。排序对代际流动性的影响比对不平等的影响更大。”
Social commentators from William Julius Wilson to Charles Murray have argued that increased sorting of people into internally homogeneous" neighborhoods,schools, and marriages is spurring long-run inequality. Cali- bration of a formal model suggests that these fears are misplaced. In order to increase the steady-state standard deviation of education by one percent, the correlation between neighbors' education would have to double, or the correlation between spouses' education would have to increase by one-third. In fact, both correlations have declined slightly over the past few decades. Sorting has somewhat more significant effects on intergenerational mobility than on inequality."
