it's a culture thing, not a drink thing
The original piece is not about supermarkets, it's about cheap booze, specifically with respect to young people.That's not the problem.
People from every nation get drunk.
The main difference is that when young brits get drunk they (according to the stereotypes) go around smashing things up and thumping people.
Contrast this to drunks from other countries who will either seduce each other, talk loudly or just fall asleep.
The problem is not the getting drunk - it's why do young brits cause so much trouble when they do it. That seems to be a cultural problem, with what people do when they lose their inhibitions, rather than a booze = violence issue, which is the way the newpapers with the small vocabularies are presenting it.
In other countries booze is *much* cheaper than in the UK (7 euros for a 1litre bottle of local brandy, for example) but you don't get the middle-class, affluent, cut-off-from-reality, sip-of-sherry-on-a-saturday-night types there saying it should be made more expensive.
Maybe people should start looking at the root-cause, cultural, issues, rather than merely hiding the problem with the simplistic idea of "more tax" to stop individuals doing things they disapprove of.
