In the process of making our childs life better (through treatment of ADD, Bipolar and depression) are we hurting or helping?

While I love my life now as a “normal” person, I would not be in the comfortable position in life that I am now had I been like this all my life. Is mental Illness, in one form or another, a lot of what provides the “drive” in our lives to get ahead? Could the “give a crap” attitude of a large percentage of our younger generation be from medicating the drive out of them?
