Technology, culture, legalization of pot, adtech, covid, there are a metric ton of factors that all had significant impact on both decreasing socialization and reduction in drinking. And lowering the birth rates, and the number of healthy relationships, healthy friendships, etc.

I'm for legalizing all drugs, regulating the sale, ensuring quality and purity, and educating the public. Cognitive liberty is sacred - but the dip in drinking has a whole lot of causes.

A healthier society would be more social and get out and drink more, I think.
