> How come teachers think they have the competence to be in loco parentis?

Multiple members of my wife's family are teachers in the local public school system. From what they have told me: they don't want to be in that place. Parents demand it of them, despite their strong attempts to push back and say "hey this one is your job as the parent to solve". So that's the reason in at least some cases, although probably not all.
