I think that's very well put, Eric. Ellis, McInerney, and don't forget their sidekicks Tama Janowitz and Mark Lindquist, did capture a certain pre-Goth/Emo immature/adolescent nihilism that was very popular in the mid-late 80's (and continues among some to this day). It was definitely facile and shallow, and maybe the times were a bit, too - but that still doesn't make for the best writing. And I think there was a lot more to the era than casual sex, greed, materialism, narcissism, and drugs. But those things were hot for a while.
