Well I'll post what I believe are some positives that are lost on the "youths" of today by not being raised in the 80's and at least part of the 70's. There are a few advantages to having grown up during that time and from earlier times.
These kids today seem to have the paradox that they should be continually entertained, are unable to realize it isn't all about them, and lastly are unable to entertain themselves.
First the fact that it isn't all about them. Even when there is entertainment, music, whatever available in a place or room, it must be suited to their tastes. They have never lived in a world where there were not 24/7 services devoted to their entertainment needs. You speak of Saturday morning cartoons and they look at you like you are an idiot. They live in a world where there are 3 a.m. cartoons on a channel whose demographic are 13-17 year olds, all day, everyday.
So they can be in a room with a 70 inch television, or with a surround-sound stereo system, or whatever but if all this equipment isn't devoted to their niche, then they often pout. They are unable to be entertained outside of their narrow band of interests.
As for being entertained, well it had better be available pretty much all the time. It also requires an incredible technological load to sustain. Anything less is their personal definition of hell. You suggest that books travel well and they almost faint on sight.
I encounter this most often when camping. I am shocked by the amount of CRAP people need to leave their homes. My own children are trying to add to our pile and 9 out of 10 times I'll tell them to take a hike on it. Go bike, go hike, go climb a rock, go stare at those damn bugs crawling around and figure out what they do.(including bite)
(A couple outings ago we were camping and we this trolley comes by carting people around. We overhear on the radio someone calling in the fact that some kids were playing with a dead bird. They were our kids)
Then the last point, entertaining yourselves. They can't do it nowadays. Television news has scared people into never letting kids leave their homes and I grew up in an age where you might get smacked if you were seen inside before dark. I can't hear a young person tell a joke. They can't seem to think, only repeat. Worse still they can't understand a joke because it might make reference to something outside their narrow band of understanding, might not make a pop reference, might require understanding, might not be slapstick, etc.
