> 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.

The Institute for Family Studies doesn't independently carry out studies. It just provides an objective review of the studies available while providing links to each study for each and every point they make, so that you can easily verify what they say. The paper you linked to, by contrast, is being actively disingenuous. For instance they claim that:

> "Other reported benefits of attendance at high-quality child care include less impulsivity, more advanced expressive vocabulary, and greater reported social competence (Belsky et al. 2007)."

You probably thought they were comparing high quality daycare to parental care, because that's certainly what they're implying. Here [1] is the paper they're referencing, which unsurprisingly they chose to not provide a link to. They are comparing high quality daycare care against poor quality daycare! Both had overall negative effects relative to parental care! In particular all non-parental childcare was directly associated with lower social competence, poorer work habits, conflicted relationships with teachers (and their mother!), and so on.

That paper itself is based on the NICHD Study of Early Child Care and Youth Development series. You can find a more casual overview of that study's findings here. [2] And an opinion piece, 'daycare - yes or no', based on an overview of the available evidence (including the NICHD study) here. [3]
