We should consider individuals aren't able to parent their kids effectively.
Would you rather trust two exhausted individuals or a huge army of trained professionals at payroll by government to parent the kids?
There is very less transfer of knowledge and the worldview of individual parents is often limited. If there is an organization parenting thousands of kids, they can run A/B tests, see results of changing incentives, able to better respond from all data gathering and long trail of past experience. A parenting organization at scale also has more power to push through effective policy faster and change legal system to remove harmful corporations (social media in this thread).
Individual parents on other hand are inefficient, start with nothing usually, don't have enough visibility, time or expertise to consider the most optimal choices. They are helpless.
