Did anyone catch Prime Time last night? They were debating this subject (along with a proposed "fat tax" on cream buns, to curb obesity, and other such Nanny state proposals).
There was a guy, whose name I didn't catch, who spoke well against such proposals. Basically saying we are one of the most expensive countrys for the price of a pint in Europe, and adding another euro onto it will not solve the binge drinking problems, but will only hurt the silent majority who are responsible drinkers. His view, which I agree with is that it's a cultural thing, and that's what we need to focus on changing. Fintan O'Toole, who was debating the opposite seemed to suggest that there is evidence that price hikes will curb this anti-social behaviour, without much citation to back it up.
Perhaps it's available to view on the RTÉ website.
