Right after the publication of The Origin of Species by Darwin there were other sciences trying to incorporate "evolution" into their disciplines & these included some of the social sciences, economics so much so that Karl Marx believed that the US would be an example of governments capable of evolving into what would be best for the working class. Yes, the US has led the way, in some ways, to make things better for the those other than the privileged...white men. But this fight will continue..
You can go down a rabbit hole with this...try Googling Karl Mark and Abraham Lincoln. Yup, they were pen pals... #history
