Darwinism is the belief that conflict between groups in society leads to social progress as superior groups outcompete inferior ones ( like survival of the fittest in nature). In 1883, Sumner published a pamphlet called "What Social Classes Owe to Each Other", saying that the social classes owe each other nothing. According to Sumner, those who feel an obligation to provide help to those under-equipped to compete for resources, will lead to a country in which the weak and inferior are encouraged to breed more like them, eventually dragging the country down. Sumner also believed that the best equipped to win the struggle for existence was the American businessman, and concluded that taxes and regulations serve as dangers to his survival. .
