Question

How was Darwinism generally and eugenics specifically used to impact america's immigration policies?

Answer 1

Answer:

People who supported Darwinism said that the government should not interfere in the working of the society by helping the poor and marginal people like immigrants because it has an adverse affect on the development of the society and does not let it go forward.

Similarly Eugenics were also totally against the immigration and the coming of people of low grades to the south america because it hindered growth and changed the mind set of the people.
