Karl Marx
The idea of a working class consciousness originated with Karl Marx. He believed that the working class was unfairly treated by the rich ruling class.
Marx called them proletarians as individuals and proletariat as a societal class.
Individuals from the working class and lower middle class are more likely to agree with Karl Marx's theories in sociology. Marx's ideas emphasize the struggle between social classes and the exploitation of the working class by the capitalist class, which resonates more with those who are at the lower end of the social hierarchy.
Karl Marx's view on capitalism was the the bourgeoisie consists of those who own and control means of production allowing them to dominate and exploit the working class.
Karl Marx argued that capitalism inherently leads to inequality and exploitation of the working class by the owning class. He believed that class struggle would eventually result in a revolution leading to a classless society where the means of production are owned collectively.
Proletariat.
All those who have to work for wages, i.e. have to sell their labour power to an employer in return for a wage.
Proletariat - taken from a Latin term for the "Lowest" working class of Rome, by way of the French version of it.
