But is it true that "it’s too expensive to modify the kid’s environment" or simply that established powers make more money by "modifying the kid"?
Costs are relative, and I think the point remains that the kid's parents are relatively powerless to alter the kid's environment significantly enough to solve the adhd problem. Thus, the decision of the cost/benefit analysis of modifying the environment vs modifying the kid falls to the "established powers", also known as, collective society.
As long as everyone with significant influence is comfortable with the status quo, there's little pressure to search for other options, even if many parents might prefer another option.
If you read through any edition of the DSM, you'll find that most disorders in it are defined by symptoms being maladaptive in the subject's current actual environment, not by objective, context-independent criteria.
