The drinking age being lowered was tied up with so many other things - Vietnam, the sexual revolution, student protests, increased drug use - that to say that everything was due to the drinking age is ridiculous.
I think that by the time this actually occurred, there was so much drug usage that it was sort of a non-event. Alcohol was for parents and The Establishment.
Obviously I'm not talking about Greeks specifically, but the culture in general. Now that the drinking age is back up to 21 and alcohol is Satan, I think that drug use is MUCH worse than it used to be when I was in school. If you're going to break the law, might as well do it up big time.
And as for his alumni comment...I think that the 70's and 80's probably saw a more diverse (I mean class-wise) group of people joining GLOs than in years previous, so if he means they are not very helpful in wanting groups to be upscale Stepfordian enclaves, I guess he's right.
