This conversation isn't getting us anywhere. I do think attitudes have changed but I also think society has changed and whereas it was safe and acceptable to turf your DC out onto the streets in the past, it is no longer the case.
What attitudes do you think have changed? If you mean the attitude that mothers should be dependent on their husbands, and give up their careers to stay at home bringing up their children, then they don't appear to have changed very much.
Or do you mean the attitude that feral youth are a product of poor mothering (as defined by a woman who works for a living and contributes to society and to her family) then that doesn't seem to have changed either.
I think it is your dismissive attitude that is the problem. You talk of your children 'breaking the mould' by staying at home with their respective children, when others, including my husband, were doing this 30 years ago or more.
You talk of the 'vital work' that your daughter does, which suggests that those who work both outside and inside the home are not vital to their children, or not providing a vital part of their lives.
As has already been said, to suggest that 'bringing up children' only happens when there is a parent on the premises at all times is ridiculous - many, if not most, parents work, and still bring up their children in a loving, caring and responsible way.
You talk of children 'roaming the streets' in the holidays when their mums are at work. They are 'in danger' and a 'menace' because they have been 'turfed out' with nobody 'in charge' of them. There is no mention of a male role model, which research has shown to be vital in preventing delinquency in young men and boys - it is all about the mother, whose place is in the wrong.
Is it any wonder that the conversation isn't getting anywhere? You accused posters of being defensive, but people do get defensive when they feel attacked, and that is certainly how your posts are coming across.
