I've been to big beer busts back when everybody was in their early to mid 20's where some drama occurred. But nobody thought much about it. We were all just kids and kids do what kids do.
I've never been to a party where adults got out of control to the extent mentioned in the OP.
The last big bash I went to was a wedding party a few months ago. It went on until late at night. There was an open bar and many young people as well as adults were in attendance. Quite a few people there had the big buzz on before things shut down for the evening, (me too) but everybody maintained their dignity,...even the young people.
In fact, everybody had a great time.
Any adult who hasn't developed the ability to drink without making a scene needs to leave it alone.
