Gosh, we still haven't sorted the country out? I don't know!
Here's some more ideas...

Increase the priority for alcohol addiction treatment in NHS (which is *vast* social problem among poorer communities) to match its social impact compared to other less socially acceptable drugs and addictions (which amount to a far smaller percentage of social problems overall).
As for junkies, give them what they actually want: i.e heroine on the NHS.
Legalise safe, healthy inspected brothels with state vetted Madames.
Freedom to both roam and camp in UK upon the land that was previously stolen from the people.
Keep repeat offending sex offenders in prison for the full length of their actual life.
Get rid of student loans and return to student grants.

Still dreaming..
Have contraception confidentially and freely available from the school nurse in secondary school.
