The Roman Catholics in the Middle Ages recruited their brightest young men for the ministry. They required celibacy to insure their full commitment to the institutional church. In contrast, medieval Jews recruited their brightest young men for the rabbinate. The families sacrificed to provide such training. Then the young men were encouraged to marry bright (or rich) young women and produce large families of (hopefully) equally bright children.
My two cents
When it comes to investing in the future, it would seem better to try and propagate your talents instead of isolating them. I’m reminded of organisations like the Vision Forum, which talk of concepts such as multigenerational faithfulness; this seems like one way of going about it.
I also like the Middle Ages concept of the talented and gifted people being encouraged to put their talents to religious purposes—rather than sports or some other secular pursuit.
