In the US, there is a large demographic shift on alcohol drinking. What I've seen is not an explicitly vocal anti-alcohol stance. But younger generations just aren't as interested in it. At the very least what they consume is different.
My personal theory is that they are scared of ending up on the Internet when they don't have control.
A common consequence of taking GLP-1 receptor agonists is losing interest in alcohol.
Now, I agree that’s not the only factor — there’s something else going on reducing alcohol consumption even in people who’ve never taken GLP-1RAs — but when you have >10% of the population taking them, that’s another significant factor contributing to falling drinking rates.
I do not know the US well enough to comment, but the US has always been a lot more anti-alcohol than (almost anywhere in) Europe.
People are broke. They can't afford the bottle or the place you go to to drink a glass. Or the Uber back/costs associated with a DUI. There's no reason to waste any of that money when you can just stay home and goon.
Of course, there are still people who go out and have a good time, or who grab a bottle on the way home from work. But as with most things these days, there's been a socioeconomic bifurcation that has split the fertile consumerist middle into haves and (mostly) have-nots. And the have-nots aren't bothering.
