Marxism is an economic and social theory based on the works of Karl Marx and Friedrich Engels that analyzes social change through the lens of class struggle. It is the antithesis of capitalism, which is defined by private ownership and profit motivation, instead advocating for public ownership of production, distribution, and exchange. Under capitalism, the working class owns only their capacity to work and must sell their labor for a minimum wage, while the products they produce are sold at a higher value by capitalists.
