There are huge local differences. In my youth and hometown, it was definitely binge drinking - and we just followed tradition. But what I learned of other areas, was actually quite similar. Healthy alcohol consumption was rather the exception, but there is a trend towards it.
And I have not been to the US to directly compare, but I cannot really say that I experienced "intergenerational knowledge transfer about responsible alcohol usage" in germany. That is, my father does not drink, because my grandfather drank too much. Does this count? Otherwise I just know too many families with at least one alcoholic and some on the way. And teenage drinking is just something teens are expected to do and the parents just try to limit the extremes. But many would be actually worried if their children never drank, because it might mean, they are isolated oddballs.
