Keynes was a proponent of eugenics. He served as Director of the British Eugenics Society from 1937 to 1944. As late as 1946, shortly before his death, Keynes declared eugenics to be “the most important, significant and, I would add, genuine branch of sociology which exists.”[136]
A lot of liberals are proponents of eugenics too.
Their disciples walk among us today.
