Members of the working class have blue-collar jobs. They are construction workers, truck drivers, mechanican, steel workers, electricians, and the like. What makes this class differ from the lower class is, first, longer periods of employment—and therefore, more fixed incomes—and , second, employment in skilled or semi-skilled occupations, not unskilled ones. Although unemployment hits all levels of the American economy, including those of skilled and semi-skilled workers, it is most common at the bottom of the class structure and increasingly less common at each level upward. They consider themselves to be respectable and hard-working and they look down upon members of the “low” class, whom they often consider to be lazy, dishonest, and too ready to exploit public assistance.

Most people in the working class have at least high school education. Many have some experience of college(especially community college), though few are college graduates. Unionization has helped the working class, but a rapidly changing economy and frequent periods of high unemployment make it difficult for most of its members to be able to increase their savings greatly. Purchasing a house for people in this class is extremely difficult, although a certain percentage may receive houses from their parents. (Home-owning rises with social class.)

A greater number of the members of the working class take relatively little satisfaction in their jobs, because much of their work is ordinary and boring. As a result, many seek their main satisfaction in recreational activities. Many members of this class would like to earn enough money to leave their jobs and start their own businesses, though few make it. Many place their expectations on their children, hoping that they at least will rise in the ladder of success.
