What ideology advocates for a classless society?

The ideology that advocates for a classless society is communism. Communism is based on the idea of eliminating class distinctions and creating a society where all property is publicly owned, and each person works and is paid according to their abilities and needs. This theory, most famously articulated by Karl Marx, argues that the capitalist system creates inequalities due to the division of society into classes, and that a revolutionary change is necessary to establish a classless and stateless society.

In a communist society, the goal is to abolish private ownership of the means of production, which is seen as the root cause of class divisions. This leads to the equitable distribution of resources and wealth among all people, fundamentally transforming society to operate on the principle of communal ownership and cooperation rather than individual profit and competition.
