I don't even know which is worse - making kids with slight ADHD take stimulants (US) or ignoring the symptoms unless they're truly a problem (bad grades and behavior aren't - you're just mentally stupid or a culturally uneducated prick in Europe).
People with slight ADD/OCD can get by, but they'll always feel something is wrong and that no one understands them (plus some may never reach their full potential), while those on meds will suffer later on...
That is because when a majority of people exhibit certain traits, those traits do not constitute aberrance. Marketing, Pharma influence & FUD peddling can make a majority feel singled out. Fear & consumption 101.
I strongly agree with 2nd point, personal accountability and good stewardship/parenting are lost values in the western world. Our youth are bored and brainwashed by the media...I was too. We're constantly reminded we are 'special'(individually, just like everyone else), we can buy happiness/solutions to our problems if we have the latest/greatest (*) and 'Not my kid' is almost a national anthem. Perception is everything & it too is easily manipulated by selfish and external influences. I too am impressionable and find much of marketing insulting, sometimes assaulting. That's why I do not watch commercial television and browse the Tubez w/ AdBlock & NoScript...I am startled sometimes when I browse without them, it's a completely different experience.
edit: reworded last two sentences
I do think that TV and internet have done nothing to help my attention span, but it might just be that I dismiss things I have no interest in. When I am doing something interesting I can focus easily for a long time.
Let's please avoid hijacking this discussion and avoid arguing about the prevalence of things like ADD (as richly ironic as these discussions may be :-)
That's a rather debatable point, I don't know anyone with any of these, frankly I think it's a U.S. thing. If it weren't for american movies I wouldn't even know it was a thing.
