Karl Marx's view on the working class

Karl Marx defined the working class or proletariat as individuals who sell their labor power for wages and who do not own the means of production. He argued that they were responsible for creating the wealth of a society. He asserted that the working class physically build bridges, craft furniture, grow food, and nurse children, but do not own land, or factories. A sub-section of the proletariat, the lumpenproletariat (rag-proletariat), are the extremely poor and unemployed, such as day laborers and homeless people.

Besides describing the social class who own the means of production, the Marxist usage of the term "bourgeois" also describes the consumerist style of life derived from the ownership of capital and real property. As an economist Karl Marx acknowledged the bourgeois industriousness that created wealth, yet criticised the moral hypocrisy of the bourgeoisie when they ignored the true origins of their wealth — the exploitation of the proletariat, the urban and rural workers. Further sense denotations of “bourgeois” describe ideologic concepts such as “bourgeois freedom”, which is opposed to substantive forms of freedom; “bourgeois independence”; “bourgeois personal individuality”; the “bourgeois family”; et cetera, all derived from owning capital and property.
