There’s a show about this. The Promised Neverland. [Redacted] raise children on farms and educate them because apparently, smarter ones taste better, but the taste drops at puberty, so they’re given 12 years max before they’re “harvested.” Saying puberty, it sounds perverse, but there’s no perverted element whatsoever to the show. It’s just straight up horror.

The show is available (at least) in both English and Japanese. There’s a film (on Amazon Prime) that is in Japanese. I’m not sure if it got an English translation. It’s better than one might expect. At one point, Amazon was going to make an English version of the film (based on the manga, not based on the existing movie) but it never happened.

Minor spoiler: they don’t care about race or gender, only IQ. The smartest ones go to the richest [Redacted], but commoners can typically get the “average” kids. Damn. That sounds Epstein as hell. It really isn’t. They’re strictly being raised as food, as cattle. (That, in and of itself, is a minor spoiler, but it’s revealed in the first episode.)
