Unfortunately I think you just have to frame thing in terms of economic measures in order to get certain policymakers to take you seriously. While some will recognize that having well-adjusted, well-educated, well-taken-care-of young children is something the government should help fund, others will take the attitude that the parents are solely responsible for that, and we shouldn't be "wasting" money on doing something the parents should be doing already. You'll also get arguments against "interfering" in parenting.

But many policymakers will react positively if you relate new policies in terms of the economic growth they promise. It's difficult to do, in this case, though, but I get why they're trying.
