This is true, this is a harsh truth.
You can see the effect in actual (real world) consequences: no one cares if you learn nothing at school and no teacher is ever fired for low learning outcome in their students. But the immediate moment a student gets hurt, for any reason, then hell is unleashed on the teacher, lawyers get involved, a the teachers is now actually risking something.
School is glorified babysitting, until university when you're on your own, age brackets mostly don't matter, and the burden of learning is onto you (professors don't care).
as a parent of a 12 and 9 year old i mostly agree. You really have to augment and reaffirm the material being taught in school outside of the school setting and with a different approach. It takes a lot of work to nurture and grow a love-of-learning vs just "did you do your homework? yes? good.". No parent is perfect though, it takes a lot of effort and trial/error to learn what works and doesn't work with your particular kid.
