This opinion post looks like a lengthy 'tu quoque' to me. Rather than present data showing how Generation Y is not lazy and entitled, he shifts the blame to previous generations for bringing us up this way. Then he points to their problems (hippie-culture and drug use) in order to label their criticism of Gen Y "hypocritical". Finally he blames capitalism for teaching us to feel entitled and self-centered. Overall, he's not so much making a counter-argument to the claim that Gen Y'ers are lazy, as he is agreeing with it whilst pointing his finger at the older generations and saying they were just as bad.
Jonathan- sorry for replying a lot later. I actually used this article for Project 1 and noted that he used the tu quoque. I agree that he's while he's trying to make some legitimate argument, he never made any sort of statement that made me want to agree with him. Rather, he just keeps complaining about the older generations perception of Gen Y with nothing to back him up.
Although this article talks about marketing generation y, the section entitled, "Generational influences within the society and culture", has some interesting ideas about the factors that influence generation y.
