Wow, I guess I just don't hang out with the same kinds of people you do (USA as well). I don't think I've ever witnessed a bar fight, and no one I know has been involved in a drunk driving crash (on either side of it). And yet I've done plenty of drinking (I don't remember much of my 30s because of it, sadly).
Instead, drinking around food was a place to get to know people.*
I agree that alcohol is a good social lubricant, and sure, it can be an aid (or even a shortcut) to social bonding. But this article made me believe that, in some East Asian cultures, alcohol is pretty much required to get them to communicate effectively about certain things. That seems... not particularly safe or healthy, not just physically, but emotionally too.
