Keynes, the eugenicist
Keynes wanted each country "to regulate the quantity and quality of its population."
"The time has already come when each country needs a considered national policy about what size of population, whether larger or smaller than at present or the same, is most expedient. And having settled this policy, we must take steps to carry it into operation. The time may arrive a little later when the community as a whole must pay attention to the innate quality as well as to the mere numbers of its future members."
("The End of Laissez Faire," 1926)
