Cultural change. Stop pushing family life as this sacred self-fulfillment fantasy it is today, but instead promote other means of salvation.

Women's equal access to sterilization would be a big one. Easy and free availability of birth control and pregnancy termination other low-hanging fruits. Improving factual constraints, education and independence: Inviting self-determined life choices and a self-serving sense of purpose.

Enforcing parent's responsibility for their children. Punish neglect more harshly. Don't allow parents to make their children's attention footprint something everyone has to endure, because "children are precious!" entitlement; no free-riding. Don't collectivize the downsides of procreation.

Basically just undo the pro-natalism ideology, religious influence and propaganda.
