"Economically productive" in what way? If you want to adopt a short term perspective of a particular nuclear family making X dollars over Y years, maybe.

But that's a rather shallow and irresponsible way of looking at things without accounting for what's better for the future society of our descendants, economically and otherwise.

What in most cases will produce a better quality of individual, a child raised at home by a loving mother, or a child shuffled off to some "childcare" to be looked after by a minimum wage worker absorbed in a smartphone half the time? (Not that all non-motherly childcare is like that, but you get the point)
