I don't think "Spanish people get to be alcoholics" is enough proof that a system works where you need to have the same currency as a poorly run country like Greece or, at this point, Germany.
(Germans are psychotically high trust and seem to just believe anything anyone tells them, like "you should shut off all your nuke plants" or "Russians are really nice and it's fine to buy all your energy from them" or "you should sell your robotics companies to China" or "you should never ever run a budget deficit".)
It's not really about the drinks and many people don't have the wine or beer. I just included them as a way to describe the informal nature. At lunch we only ever have one (in France even the canteens serve wine, it's quite normal). And we don't do it every day :)
It's just about enjoying life being the primary goal, not amassment of material goods.
