I think that extremely stringent drinking laws would do Britain the world of good. It is staggering what alcohol-related problems cost our economy, indeed the extent of the problem is so wide and varied that it is almost incomprehensible - everything from the burden its puts on the NHS, to the prison system, to the welfare system, to days missed off work... not to mention the indirect effects it has on peoples' lives - broken marriages, spousal/child abuse, unwanted pregnancies, mental health, unemployment, etc. The drinking culture in Britain is shocking, you can't compare it to what you see in Souther Europe, or indeed most of the rest of the world. What is going on today is well beyond what is acceptable.
Remember this gem?
I wouldn't go so far as to suggest outright prohibition, since that would be totalitarian. However, it is well within both the spirit and the tradition of those governments at Westminster that secured and protected our liberties for hundreds of years, to take very harsh measures against the production and distribution of alcohol.
The aim in such measures should be to foster a healthy drinking culture. To allow our small, traditional pubs to flourish, while slamming the big chain-pubs and the night-clubs which seem to be increasingly ubiquitous. Allow our small, traditional breweries to recover while slamming the big multinational corporations that have shut them down.
This would take a multi-pronged approach. A good start might be to:
1. Ban any company above a certain size from producing alcohol - this removes competition from local brewers, while also taking the cheapest alcohol (and thus the most problematic) off the market.
2. Ban chain pubs - same reasoning as above, these tend to be the sort of places where our binge drinking culture manifests itself, not the more quaint local establishments.
3. Ban certain alcohol imports - eg cheap foreign trash that fuels problem drinking, while allowing the connoisseur to get their French wines and German lagers. A simple rule to avoid red-tape would be to have a minimum retail price per unit - anything below it isn't allowed.
4. Subside alcohol advertisements - help the local brewers to get their name out and re-market alcohol as part of a different experience - not as something to be part of a 'night out', but as a traditional beverage to be enjoyed with a family meal.
5. Stop going overboard with the alcohol education in schools - seriously, its counter-productive. It makes it seem cool and risky and rebellious, and highlighting the dangers doesn't really counteract those points - kids see adults drinking it all the time so they know it won't kill them, at least not right away.
