America is becoming a more divided society – divided not only between whites and African Americans, but also between the 1% and the rest, and between the highly educated and the less educated, regardless of race. And the gap can now be measured not just in wages, but also in early deaths.
凯斯-迪顿的研究成果表明这种理论已经不再适用。美国正在成为一个更加分化的社会——不仅白人和非裔美国人之间分化，1％和剩下的人之间分化，无论种族的高学历和低学历之间也分化。而如今这些差距不仅可以通过收入，还可以通过死亡寿命来测量。原来白种美国人同样也会因收入下降而寿命变短。
