Social Darwinism- the theory that individuals, groups, and peoples are subject to the same Darwinian laws of natural selection as plants and animals. Now largely discredited, social Darwinism was advocated by Herbert Spencer and others in the late 19th and early 20th centuries and was used to justify political conservatism, imperialism, and racism and to discourage intervention and reform.
I don’t understand why you’re advocating for social darwinism, but it may be my lack of communication skills at fault.
