The European attitude is completely different from most Americans
What is the American mentality of drinking?
Put as much down as fast as possible.
Drunk driving is ok if you get away with it.
Overall alcohol seems to still be considered a guilty pleasure only people of a certain age, in certain places, at certain times can drink.
Lastly youth consumption of alcohol is already huge and most kids learn the pros and cons of drinking in high school or college.
Our cultural attitudes towards alcohol need to change before the drinking is lowered (those attitudes are the reason it was raised in the first place!)
