Doctor, Timmy is getting in trouble in school.
How does he get in trouble?
The teacher says he is too active and might have ADHD.
Have you seen a counselor about this?
No, we can't afford one!
Well, let's try a round of Adderall...
This might seem oversimplistic, but I teach a high school 'behavior intervention' classroom and deal with parents all the time who have the same concerns/issues. More often than anyone will admit, many of the issues related to behavior have to do with cost/consequences...and parents who will not/can not engage the reality of their children's behavior (It's not their fault! They are just picking on Timmy!).
Often, the teachers are just as guilty making these recommendations as the doctors--it is illegal for a teacher to recommend/suggest that a child has to be medicated to attend school, but it happens. And many 'poor' parents do not have the background/education to question the recommendation. So, they go to the doctor and tell them that Timmy has to have medicine to attend school.
The fun part in all this is watching the merry-go-round of meds that a child will/will not take to modify their behavior. For some kids, it is necessary to function. For most, it is not.
By the time they get to high school, many are dependent on the meds to function.
