What according to Marx is the main difference between the feudal society and an industrialized society?

According to Marx, the main difference between feudal society and industrialized society lies in the mode of production and class relations. In feudal society, economic power is based on land ownership and agrarian labor, with a clear hierarchy of lords and serfs. In contrast, industrialized society is characterized by capital and wage labor, where the bourgeoisie (owners of production) exploit the proletariat (workers). This shift leads to different forms of class struggle and social dynamics, fundamentally altering the nature of economic relationships and social classes.
