Parenthood is a political office grounded in demands of liberal-egalitarian justice, rather than some natural or personal relationship between the child and adult. For a community to respect children as equal members throughout their lives, it must ensure each child is in the custody of an adult with the duty to provide care and guidance. Children cannot judge or pursue their own conception of the good, so each child needs some adult authority to judge how they use their primary goods to flourish during childhood and develop into a thriving adult. That authority must be created and structured by law. The authority must be cabined to ensure parents satisfy children’s entitlements, which only the community can legitimately define through its collective judgment. Law must also structure the parental office appropriately. Adults can make substitute judgments to guide the child’s life only if a few caregivers are responsible for a few children. In other words, all children have a political right to a parent.
