Question

Quizplus · Accepted Answer

The proletariat is a social group consisting of individuals who sell their own labor to earn wages. They do not own the means of production and are dependent on capitalist employers for employment. The bourgeoisie, on the other hand, owns and controls the means of production and employs the proletariat to produce goods and services. Bureaucrats are individuals who work for the government, and capitalists are those who own and invest capital in businesses to make a profit.
