...okay, yes those particular kids clearly need someone to work with them on 'that is awful and you don't actually have to put up with it', and that's going to require getting them into a situation where that's, y'know, true, for long enough for them to work out that they can believe it. But in a sensible society? That doesn't even happen, because as soon as a parent starts being a pain to live with a kid can just leave, no specialized jobs necessary.

(Also, the bit where the kid she moved was able to go right back to their family? Not an accident. Removing someone from imminent danger of assault is a different thing from abducting them.)
