Your assertion that only families among "the wealthiest in the world" have non-school childcare arrangements is incorrect.

I agree that everyone should have access to better child-rearing opportunities than are offered by school, especially public school in North America. I'd love to see homework eliminated, more time in school devoted to play, more tracking & opportunities for everyone to develop their strengths (be they calculus or auto mechanics), and the elimination of compulsory secondary schooling (let the kids come who want to come & make it rewarding enough that they do, rather than threatening to jail their parents to bring them to heel).

I am ignoring the aspects of your comment directed towards me personally.
