Quick bit of relevant threadomancy (to prevent me starting a new one).
So, proposals are underway to offer a minimum unit price of alcohol, suggesting around 50p.
Now I'm not economic or health expert, but I'm not sure this is actually the best answer. What is, I hear you ask?
Simple. To stop binge drinking, don't whack up the price of cheap booze.... Just limit the sale of it specifically to Off Licenses and Pubs. Boom. They tend to have the biggest overheads. No more booze as a loss leader, making it already more expensive without unnecessary legislation. And as an upswing, the sadly maligned, and generally exceptionally responsible Publican and Licensee will see an upsurge in sales, protecting jobs. Supermarkets not being able to sell booze won't affect them one iota, on account they already flog it at a loss in order to lure people in in a childish competition.
Could pubs then lower their prices? Sure they could. But you'd still have (for the most part) a level headed publican being able to refuse further service.
Biggedy biggedy bong, several problems tackled with a single piece of legislation, and to the satisfaction of the vast majority I'd wager.
