Neither Fascist Italy nor Spain adopted eugenics as an ideology central to their form of government the way the National Socialist did. However, socialist and progressive nations such as Canada, Sweden, Denmark, Finland, and Norway did adopt and implement eugenics. This is because eugenics is the safety valve of a centrally planned economy. Central planners like John Maynard Keynes fear a population that is not as meticulously planned as the economy. They fear the unproductive sectors out-breeding the productive sectors of the population. This is also why Keynes was a lobbyist for the British eugenics movement both before and after The Holocaust.
