Keynes was actually an evolutionist -- he was vice president of the Eugenics Society. He was also gay. His mom was a member of a Cambridge-affiliated eugenics society. His nephew, who was the son of Charles Darwin's grand-daughter, was a member of the Eugenics Society too. Keynes was a fan of Malthus and Galton.
LOL. It all fits the profile of justification of self - relentlessly and dogmatically building theories to support one's own presuppositions, while ignoring what would routinely be considered facts.
