If the "known eugenicist" is who I think it is, then he isn't.

The general idea, as explained by the late Hans Rosling, is that if you educate people (including girls) and help them to lead better lives then they will naturally have fewer children. They do this of their own free will.

Rosling says: "only by raising the living standards of the poorest can we check population growth". [1]

If there is a very high probability that half your children will die before they grow up, then it makes sense to have twice as many children. If you expect every child to grow up and thrive, you won't do that.

This has already happened in most developed countries, with no eugenics and no eugenicists involved. Most people in the west now have fewer children than their grandparents had.

I really don't see a problem with less-developed countries enjoying exactly the same sort of progress as we've already had.
