What is the primary focus of Karl Marx's theory in sociology?

Karl Marx's theory in sociology mainly focuses on the idea of class struggle and how it shapes society. He believed that society is divided into different classes, primarily the bourgeoisie, who own the means of production, and the proletariat, who are the workers. Marx argued that the conflict between these classes drives social change and leads to different economic systems throughout history. For example, he thought that the struggles of workers against their employers could eventually lead to a fairer society where resources are shared more equally. By focusing on these class dynamics, Marx aimed to show how economic factors influence social relationships and structures.
