Even with all the talk recently about how successive governments have failed the children of Britain, I still haven't heard any reasoned arguments about what can be done to change the situation.

The excessive drinking culture we have isn't fixed by controlling the price of alcohol or pub opening hours, and underage sex doesn't disappear with better sex education. These are all part of the culture that people are brought up in and can't be regulated away. Yet I've never heard anyone discuss how we can create a more positive culture.
