Answer:
The belief that white, wealthy, Anglo-Saxon Americans were biologically superior to other groups fueled many social and political trends of the Gilded Age.
Step-by-step explanation:
The explanation they arrived at was that businessmen and others who were economically and socially successful were so because they were biologically and socially “naturally” the fittest. Conversely, they reasoned that the poor were “naturally” weak and unfit and it would be an error to allow the weak of the species to continue to breed. They believed that the dictum “survival of the fittest” (a term coined not by Charles Darwin but by sociologist Herbert Spencer) meant that only the fittest should survive.
