There are millions of parents, while there is only one Mark Zuckerberg. There's no such thing as parents collectively deciding to take responsibility, and it's unfair to the children to just expect them to have good parents. It's a classic case of a coordination problem.
What? It's not that there's just one Zuck, it's that there are fewer Zucks than parents. The strategy would be the same if there were 5 Facebooks competing for market share.
Ironically, it could be argued that it's easier when Facebook is the only player in town; otherwise the argument might be "But my competition does it! It's a race to the bottom - I can't compete if I act ethically!"
>and it's unfair to the children to just expect them to have good parents.
Also unfair because some parents are not rich.
Some aren't living in the right place.
Some are not highly intelligent.
Some are not woke enough.
Indeed very very unfair.
Lets hand over the responsibility to companies or to the state. Communistic coordinated child parenting probably isn't gonna make it better for the children but at least its fair.
The point is that the premise is nonsense. You cant justify top down ruling by the fact that some parents aren't good parents.
If you go that route you could top down rule everything because some people are not good people. The end goal would be some kind of totalitarian government.
