A long-term prospective study of 456 inner-city men tested the hypothesis that extreme poverty and chaotic family life produce a self-perpetuating underclass. Men from chronically dependent and multiproblem families were on average indistinguishable by midlife from the children of more stable working-class families in terms of mean income, years of employment, criminality, and mental health. Although attained social class was somewhat lower for the disadvantaged, given the opportunity for steady employment and occupational mobility, the children from multiproblem welfare families did not inevitably perpetuate their initial disadvantages.
一项针对456名市中心男性的长期前瞻性研究检验了这样一种假设:极端贫困和混乱的家庭生活会产生一个自我延续的下层阶级。长期依赖他人且问题众多的家庭中的男性,到中年时,在平均收入、就业年限、犯罪率和心理健康方面,与家庭较为稳定的工人阶级家庭的子女相比,平均并无差异。尽管弱势群体所达到的社会阶层略低,但如果有稳定就业和职业流动的机会,来自问题众多的福利家庭的子女并不一定会延续他们最初的劣势。
