<P> The middle class is the most contested of the three categories, the broad group of people in contemporary society who fall socio - economically between the lower and upper classes . One example of the contest of this term is that in the United States "middle class" is applied very broadly and includes people who would elsewhere be considered working class . Middle - class workers are sometimes called "white - collar workers". </P> <P> Theorists such as Ralf Dahrendorf have noted the tendency toward an enlarged middle class in modern Western societies, particularly in relation to the necessity of an educated work force in technological economies . Perspectives concerning globalization and neocolonialism, such as dependency theory, suggest this is due to the shift of low - level labour to developing nations and the Third World . </P> <P> Lower class (occasionally described as working class) are those employed in low - paying wage jobs with very little economic security . The term "lower class" also refers to persons with low income . </P> <P> The working class is sometimes separated into those who are employed but lacking financial security (the "working poor") and an underclass--those who are long - term unemployed and / or homeless, especially those receiving welfare from the state . The latter is analogous to the Marxist term "lumpenproletariat". Members of the working class are sometimes called blue - collar workers . </P>
