Class struggle refers to the conflict between different social classes, primarily between the working class and the bourgeoisie. This struggle arises from the differing interests and economic power of these groups, often leading to tensions over issues like wages, working conditions, and wealth distribution. Historically, class struggle has been a driving force behind many social and political movements, including labor unions and socialist movements. These efforts aim to address inequalities and improve the rights and conditions of the working class, challenging the dominance of the wealthy elite.
