I've actually heard from other people that the older engineers, as you say 30-50, are tremendously better as well. It seems that most of the complaints center around younger guys in 'softer' professions and that is interesting to me. I kind of wonder how the intersection of current feminism is hitting younger guys. I am not by any means excusing the behavior, but I wonder why it is getting worse instead of better. I'm really interested in developmental psychology so it's quite a pattern to note. :)
