What if you could arrange it such that people who are really lucky married other people who are also really lucky? (You could measure luck in all sorts of ways.) What if you did this for ten generations?
Wouldn’t the great9 grandchild of the luckiest couples on Earth be the luckiest kid on Earth?
The luckiest kid on Earth would be a nice story for children.
Aside
I’ve stolen the idea of breeding for luck from Larry Niven’s Ringworld, a science fiction novel I read an-astonishing-to-me 25 years ago. It’s quite a sticky idea to have stayed with me all these years.
