I think it is that parents are expecting perfect kids like these are normalized product you can buy from factory. They are panicking when their kids deviate from their perceived norms, and seek medication to fix the "problem".
ADHD, hyperactivity etc were non problems 40 years ago and got no treatment.

Lack of ADHD and hyperactivity being notable problems had more to do with the lack of medical study and treatment rather than the lack of cases. 40 years ago, physical abuse was still the norm and people believed you could punish bad behaviors out of a kid. Going even further back any boy thought to be "deviant" or "troubled" would be sent to mental institutions or bootcamps.
