It seems to me that a lot of the problems result from failing families - families produce troublesome kids, and families also present the greatest threat to children's wellbeing (as
Larkin pointed out - includes swearing).
I'll never live to see it - but I reckon we need a better way to bring up future generations rather than relying on family units to do it.
If the state raised children, we'd have a more equal society with better life-chances for the next generation.
(Although I recognise this is a minority view at the moment.
