Answer :
In the Marxian framework, the proletariat consist of those who sell their labor because they have no other way to earn a living. They are employed by the bourgeoisie for wages and experience alienation from the work they perform and the products of their labor.
The proletariat in the Marxian framework are those who must sell their labor to survive because they do not own means of production. The proletariat is defined as the class of people who are propertyless and must sell their labor power to the bourgeoisie to obtain the means of subsistence. The owners of the means of production, known as the bourgeoisie, employ the proletariat for a living wage.
This system results in the proletariat lacking control over their work and the value created by it, leading to a condition known as alienation, where workers see others and themselves as commodities and feel a sense of disconnection from the work they do and the larger society.
The factory system of the Industrial Revolution solidified this dichotomy, placing the proletariat in a position where their only form of freedom was their legal ability to choose which capitalist to sell their labor to, thus perpetuating their economic dependence on the capitalist system for survival.
