i guess it is whether you believe that the state (and teachers are intrinsically a part of the state) should broaden even further their authority to teach children about marriage and relationships and child rearing. I am not comfortable with that at all.I think that is a role for parents and extended family . I know that this is not happening as much as it did in the past but parents on the whole over the last 40 years or so have had their responsibilities and authority over how they raise their children systematically stripped to the point where the culture in terms of who is supposed to do what has become so blurred that a significant amount of parents have basically accepted that the state have the lions share in how their kids turn out . But there is a role for parenting and marriage classes for the parents of children on a voluntary basis. These classes unfortunately are only usually available at the end of a relationship break down (at least in the UK) when the situation has become chronic. And they are usually at a cost which will indirectly discrimminate against the poorer member s of society.
Its a tough one to crack and thats for sure. Its even tougher being a responsible parent today than it ever was.
