Another thing that would help would be to ban alcohol advertising.
But nothing which would actually have the effect of reducing alcohol sales would actually be implemented. The government just want an excuse to gouge us a bit more, while being seen to be doing something about binge drinking, even if it is ineffective.
Anything that has the possibility of hurting the publicans bottom line would cause the pub owning back benchers to rebel, just as they did when their monopoly was threatened by the Café Bar licence proposal.
Lenihan's job is about acting concerned and being seen to do something, without actually doing anything effective. If, in the process, he can get a few extra quid into the government coffers, so much the better.
