Well it's a fact that you do get more open and relaxed with alcohol. The barriers go down.

And over the lifetime people almost all the time had alcohol when they where at parties. You start to associate alcohol with fun and parties.

Of course this is generalized and depends on cultures and groups.

That's what I like about them young Gen Z, they drink less alcohol. Sadly they also socialise less.

I once heard a story that Inuits in Greenland did not have access to alcohol so everyone could drink. Instead only half drank, and the other half had water but where allowed to act as if they where drunk. I'm not sure this is real, but I can see it happend.

That's probably it. It's a ritual. A costly one though, in terms of money as well as health. Direct cost (liver, brain cells, ...), as well as indirect (accidents, fights, ...).

I wouldn't celebrate to soon. Every movement eventually spawns a countermovement. Next gen might be the most booze consuming ever.
