Labor class -past, present, future

Working class (or Labouring class) is a term used in the social sciences and in ordinary conversation to describe those employed in lower tier jobs (as measured by skill, education and lower incomes), often extending to those in unemployment or otherwise possessing below-average incomes. Working classes are mainly found in industrialized economies and in urban areas of non-industrialized economies.
As with many terms describing social class, working class is defined and used in many different ways. When used non-academically, it typically refers to a section of society dependent on physical labor, especially when compensated with an hourly wage. Its use in academic discourse is contentious, especially following the decline of manual labor in postindustrial societies. Some academics question the usefulness of the concept of a working class. The term is usually contrasted with the upper class and middle class, in terms of access to economic resources, education and cultural interests. Its usage can be derogatory, but many people self-identify as working class and experience a sense of pride similar to a national identity.
