The impact of the Industrial Revolution on social classes in the modern world was profound and transformative. It marked a transition from agrarian economies to industrialized ones, resulting in the emergence of a distinct working class and a burgeoning middle class. Factory work drew millions into urban areas, creating new social dynamics and economic opportunities. However, the revolution also led to stark inequalities, with wealthy industrialists amassing significant power while many workers faced difficult conditions and low wages. This disparity drove labor movements and social reforms, ultimately reshaping class structures and contributing to the evolution of modern society and its economic systems.
