Seems to me that many do permit more or less a stranger to watch over their children in public schools. I mean really how much can parents possibly know about all the people that are watching over them. Have they sat down on a personal basis and gotten to know them. Likely not. And if they did would they let them teach. I am not trying to beat teachers up as I believe there are good ones. I'm just saying, how well do we really know them. I'm inclined to believe that if we knew them better we would he getting better results and less left leaning students graduating. Just saying.
Perhaps instead of looking at the parenting in Scotland they should be looking at the parenting in several central amerikan countries where parents are paying large amounts of money to send their children away with coyotes on an 1800 mile trip to paradise.
