How did Darwin theory of survival of robber barons?

Darwin's theory of evolution, particularly the concept of "survival of the fittest," has often been misapplied to social and economic contexts, such as the era of the robber barons in the late 19th century. In this context, it was used to justify the aggressive business practices and monopolistic strategies employed by industrialists like John D. Rockefeller and Andrew Carnegie. Proponents argued that their success demonstrated natural selection in the economic realm, where only the strongest and most ruthless would thrive. However, this interpretation overlooks the social and ethical implications of such practices, as well as the role of government regulations and societal welfare.
