I heard this statistic (fwiw) here in the US: 10% of a liquor store's customers are responsible for 90% of the sales. That doesn't mean some fraction are drinking 10X what everybody else is. It means some fraction are drinking 81X what a normal person does. So yes it's a bipolar drinking culture in the US. Some folks drink, a lot, way too often. The rest drink occasionally or not at all (the liquor stores don't count those that never go into the store).
