working class

The working class is a group of people in a social hierarchy, typically defined by earning wages or salaries through their ability to work. Members of the working class rely primarily upon earnings from wage labour. Most common definitions of "working class" in use in the United States limit its membership to workers who hold blue-collar and pink-collar jobs, or whose income is insufficiently high to place them in the middle class, or both. However, socialists define "working class" to include all workers who fall into the category of requiring income from wage labour to subsist; thus, this definition can include almost all of the working population of industrialized economies.
