Have you taken a look at the study this article is written about?

I'd agree that it makes intuitive sense that childcare could do better than exhausted working parents, and possibly even emotionally drained stay-at-home parents, but another poster pointed out that this study seems to say "people who can afford daily childcare have children with better outcomes" -- which might correlate pretty closely with "wealthier people's kids have better outcomes", which the research already told us.

As an aside, these kinds of discussions (where HN talks about the world's social problems) are the second reason I come to HN. I'll get exposed to great worldviews, from generally smart people, expressed by people who speak my language.

And child care, together with the possibly related problem of currently worse outcomes for children of single-parent families, are social problems that are potentially immensely valuable for society to solve.
