That's only a waste if you don't value the other castes.
The whole program of artifical birth is designed to isolate the non-warriors from the horrors of war, by ensuring that war is only fought by mass-produced warriors who are insulated from the consequences of death by the clan system.
A normal man, with a family who cares for him, and depends on him, for him to go to war and die would be a tragedy that would harm everyone involved. But the clan way, with a trueborn going to war, can only find fulfillment through death in battle. with that in mind, they can be extremely stringent in their filtering process, ensuring that people who are not diehard warriors, cut out to be the elite of the elite are given a life with a different purpose, a safer one.
Counterpoint-the whole program of artificial birth is designed to isolate children from outside supporting structures and indoctrinate them in a culture of ultra-violence, where they are encouraged by artificial scarcity and beatings, and only able to retaliate against those lower than them on the totem pole of violence. Then, you shed dozens of boys and girls halfway or more through this process. (standardized test performance in the fifth grade *generally* predicts standardized test performance in the 12th grade, so go ahead and weed early, especially if you can genetically and epigenetically predict final body size and strength.) Then, you take these children, who can only find worth in battle, and throw them into a lower caste. They will grow up there, without parents, without support structures. Many of them will take their own lives. Many more will beat their wives and husbands. Some will push their own children into freebirth sibkos, which will instill the same trauma, but have much lower chances of being anything more than coffin-stuffers. The violence and abuse of the Sibkos spills out into greater society, and those who graduate successfully are *still* traumatized and are expected to rule over those other castes after yet more murder on their parts.
Read this article on the spartan
agoge to get some idea of what the actual consequences of this kind of systematic child abuse/indoctrination is-products of the sibko ought to be ' emotionally stunted, prone to violence and social isolation – as well as conformist and inflexible'. And what do you know, the products of that system are generally so!
