Let's not forget the role of parents who don't want to exert the energy of parenting. So when they have a strong willed child they take them to the doc "I can't control him, do something!" And the doc goes along, labels the kid ADD or such. Next come the meds. That takes less effort on the parents' part.
I completely agree. Nowadays there's a pill for everything. I don't know what the hell restless leg syndrome is but if I ever figure I have it. A perfect life is just a pill away.
