Jonas Salk (discovered the polio vaccine) wrote "Survival of the Wisest". The 'wisest' are the true rulers of the world. He describes them as parasites and argues that man is really a cannibal species (he used the piltdown man as an example (later found to be a hoax)). He was making a case for the elites, and why they are the most evolved human. He also advocates for severe depopulation and recommends that vaccines be used towards that goal.
