By "European approach" I don't think you mean "European approach." The drinking cultures in, say, the UK, Sweden, and Italy are quite different. In Sweden it's relatively unusual to sit down with a glass of wine for lunch, and the UK is much more beer oriented than Italy.
In any case, does your logic extend to other forms of alcohol? Only a few decades ago it was common in the US to have a three martini lunch, and watching the TV shows of the 1960s shows an incredible amount of leisure-time drinking. See http://www.harpiesbizarre.com/cocktailhour.htm for examples from Bewitched. Has the amount of binge drinking and DD rates in the US gone up now that those are no longer as culturally acceptable?
By "European Approach", I'm talking about the more acceptable normalization of alcohol as a food item. Americans treat alcohol like either radioactive poison or a moral suspension drug. I've noticed in my various times in various parts of Europe that alcohol consumption general starts earlier and the usage of it is generally better moderated in consumption than in the U.S. (there's an entirely different pattern for alcohol that I've seen in East Asia as well).
Sure, Swedes might not sit down and drink wine for lunch, but the grape/grain alcohol divide kind of is the cause of that. But I'm old enough to remember being able to purchase beer in Germany as soon as I was tall enough to look over the bar and get the bartender's attention.
You are right that alcohol consumption, particularly hard alcohol seemed to have been more common in the 1960s. Overall traffic death rates were very high before the Ralph Nader auto safety revolution, often for stupid reasons. I'm sure somebody has done a good analysis of the complex reasons why, but my hypothesis is that commonplace drinking has gone down as car safety has gone up, being attributed to traffic deaths by organizations like MADD, etc. It's become less socially acceptable to drink during working hours.
Understood. My comment is that "European Approach" is a poor shorthand for what you mean. In the UK, for example, alcohol seems much more like a 'moral suspension drug', as the innumerable accounts of drunken Christmas parties from the UK, or stories like http://metro.co.uk/2010/11/01/aebooze-asbosae-for-drunken-yo... ("We remain concerned about the number of alcohol-related incidents and the drink-fuelled violence and disorder that blight many of our towns and cities") seem to attest.
You mention Germany, but as http://en.wikipedia.org/wiki/Alcohol_laws_in_Germany points out, "The German laws regulating alcohol use and sale are some of the least restrictive ones in the world." I don't think it's appropriate to use an extreme as if it is representative of the average.
