Answer:
Social Darwinism was a philosophical position that justified the harsh treatment of poor workers (labor), and the exploitation and enrichment o a few capitalist individuals (the owners of the businesses).
Social Darwinists thought that business owners were inherently superior to workers who did not own capital, and thought that they had the right to step on workers just like a lion catches a zebra in the wild. Social Darwinism is simply the adaptation of the theories of Darwin to explain the natural world, into the social world.
