The correct answer is - schools require conformity, and a child's individuality might fall outside those norms.
According to Fadi Haddad, schools want their students to all be the same, to conform, behave in the same manner, look and talk the same. So if a child falls out of this category a bit, it needs to be medicated in order to calm down and be like the rest of the students. This is the social factor of medicating ADHD, according to this psychiatrist.
