i believe majority of generation y remembers life before technology, and i believe that a lot of people in this generation would love nothing better but to go back in time and make the most of their late-childhood and/or teen years.
nobody remembers life before technology. fuckin' nobody, especially those in generation y. cars, telephones, radios, televisions? all that shit existed back then, certainly far beyond when generation y began. sure, it's becoming ever more common, particularly in the hands of children, but it not being there? nah - and this isn't me being an asshole and pointing out that shovels and even spears are in fact technology of a sort.
also, people having nostalgia for the "good ol' days" isn't exactly new and i honestly doubt it has much to do with technology, after all, modern technology is remembered fondly by many people that closely grew up with it - remember that old gameboy or nintendo 64 and how it "practically raised you," and when you were angry at that bully at school that you always had mario and your favourite pokemon to cheer you up? of course you do. you probably don't remember things like how much you hated that bitch in second grade or how much it hurt when your parents divorced, though, or at least the memory is foggy/suppressed.
people forget the bad things about their pasts and remember the great parts about it; that's what gets all of these people bitching about "back in my day..." and whatnot, even though things may have been objectively worse "in [their] time," - this is noticeable particularly in childhood when people are generally "carefree" and thus lack the responsibilities and gravity of the "real world" on their shoulders and are thus generally more mentally liberated due to lack of overall concern, and thus their not really knowing how the world works in any way more than their very narrow perception of it.
also, his post wasn't so much to demean the baby boomers so much as to say that generation y has actually valid reasons to be pissed at their current situation. i honestly don't pay a terrible lot of attention to global economic trends over various decades, but it doesn't seem inaccurate.
