Social Darwinism is the theory that B) life consists of competitive struggles in which only the strong survive. This theory applies Darwin's theory of natural selection to the social and political world. Those who supported this idea believe that in the social realm it is the responsibility of individuals to succeed and that those who are strong enough will and those that are not will fail. Those that support this theory did not support government programs to help the poor and other socially beneficial government policies.
