I guess I also wonder at the amount of stuff that teachers are expected to do now - as you say Trill, taking over so many aspects of parenting. It's not really feasible. So yes, they spend a lot of time at school, but are schools and teachers really equipped to instill values? They can talk about values or ethics, and they can enforce particular rules in the classroom, but does that really have the same effect?
How do you teach values except by example?
But, yes, I suppose I would prefer a school to follow a similar set of values to my own.
