> You've gone from efficiency and economies of scale, to a "professional" outperforming an "amateur."

These are one in the same. Economies of scale work because of specialization.

> Raising a child is not like making a widget. Endless studies [1] demonstrate that more early non-parental care leads to worse outcomes in just about every single way - worse behavior, health, attention span, long term higher likelihood of police encounters, and much more.

You didn't link to any specific study but that's the exact opposite of what the search results say [1]. The results suggesting that daycare has negative effects all seem to be from the Institute or Family Studies [2] which is a conservative think tank promoting traditional gender roles. If you have credible sources that state otherwise, please share them directly.

> Obviously not all parents are created equal, but it turns out that even bad parents tend to be better than non-parental care, especially early on.

Yeah, you're gonna need a specific source for that claim.
