Should not be happening in schools by teachers.
1) That kid is the parent's property
2) That teacher probably has 20 stands of AIDS
3) Just teach my kid Math, English, and Athletics mostly
Yes they are. Else some other entity will claim them like the Government or Teachers. You better come in with an army of unblemished Donkeys and an Engineering Degree as offer for one of my daughters.
If you didn't make my kid Smart and Ripped then how are you useful to me?
So then what's the point of school if I send my kids there 8 hours a day, 5 days a week?
I'd just fill in the gaps or amplify whatever they already know.
