已预测美国将出现更大的收入差距
This has created “a paradox” in that recruiting first-generation students, but then watching many of them fail, means that higher education has “continued to reproduce and widen, rather than close” an achievement gap based on social class, according to the depressing beginning of a paper forthcoming in the journal Psychological Science.
根据即将发表在《心理科学》期刊上的一篇论文令人沮丧的开头，这种做法创造了一个‘悖论’：招收第一代大学生，但随后却看到其中许多人失败，这意味着高等教育‘继续复制并扩大，而非缩小’了基于社会阶层的成就差距。

但这篇文章实际上相当乐观，因为它概述了解决这一问题的潜在方案，提出一种方法（涉及一个几乎不花成本的一小时项目）可以缩小第一代大学生与其他学生之间63%的成就差距（以成绩等因素衡量）。
