It just occurred to me the extent to which Darwinism - itself based on Adam Smith's writings about economies and related ideas of survival of the fittest, etc. - naturalized Capitalism as a "normal" or "natural" social system. As its cultural hegemony has increased, non-capitalist nation-states seem increasingly "unnatural" and thus the call to forcibly overturn those regimes is supported by the seeming "unnaturalness" of their social systems.
