I think the idea is that many totalitarian systems treat every child as an orphan, in some cases taking them physically away from their parents and then have people look after the children as a job. Hence the comparable situation.

And, of course, all such systems I've ever read about do not care about the practical limitation of 1 caretaker per 1 child. I believe youth services in the Netherlands, for example, has 1 caretaker (effectively available to the child) per 15 children, or 7 or 8 if they're trouble. Does this work? No, of course not. They don't care. The kids grow up caring for nobody, probably because effectively nobody cares for them. One person watching 15 children can only hope to prevent disasters, if that, they cannot provide decent attention to children. By the standards of this article, there's probably 2 people who work in the same "group". If there's a third one, they will be shared between at least to groups. So 2 to 2.5 per 15 children ... comes to one parent figure per 7 children, which is a third to a fourth of the care children would receive in even a huge family, and much less than in a small family.

This idea is just wrong. Wrong isn't strong enough, it's conterfactual. At most some of them treated female bodies as owned by the state. I do not remember any example of totalitarian society where a child of a political opposant would be treated the same as any military child. Maybe Salazar? But even then, it was so corporate-aligned I doubt children from owners were treated the same as children from workers at anytime.
