In chapters 3 & 4, Foner discusses two subsectors of the American working class that are seldom considered by the very patrons they serve: immigrant workers and female employees. Ironically, throughout American history both immigrants and women have been crucial to the survival of the US economy. Originally, immigrants were underpaid for taking on lowly tasks that the average American-born worker would refuse to do. These jobs included harsh conditions, conniving supervisors and very little room for promotions or growth. Although many immigrant works were treated as disposable entities, this was due to the fact that so many immigrants were available and desperate for work; had these immigrants not been present to support the lower tiers of the US workforce, the stagnancy they suffered would have been passed onto the native American youth as they were forced to fill these jobs rather than peruse education and more appealing careers. Women also played a similar role in completing the necessary, but unappealing or unflattering tasks, (for example, dress making in a hot, crowded factory for hours without breaks) and even continued on to fill the jobs left behind by soldiers once the US men and boys were shipped off to war.
Today, although both female and immigrant employees are still stereotyped and discriminated against, and increasing emphasis on the importance of these special interest groups is becoming more and more apparent. Many affirmative action scholarships and employment-assistance programs favor female and/or international students, to such a point that many Americans complain about feeling disadvantaged and unable to compete. In the event of a recession, when Americans are more desperate that ever to find work, more and more jobs are outsourced to foreign employees who offer a wider range of/better quality skills, often for a competitively lower price. The very groups that were originally shoved to the bottom of the employment pool are finally beginning to float.
