The actual offense is making handwavy statements like 'we're drugging kids for not wanting to concentrate on things they're not interested in'. ADHD is not as simple as that. And for people affected by it, even interesting things are often physically impossible to concentrate on - it's incredibly frustrating and a debilitating condition to live with without medication (depending on severity, of course). A different environment wouldn't solve the problem.
Aside from all that, I agree that forcing everyone to conform to the narrow range of 'normal' in general is less than ideal, but since this is the way current society is structured down to its very basis, the idealistic idea of turning that on its head is probably not very helpful to those presently impacted by it.
I don't know much (anything, really) about this so please don't construe my comment as one of any judgement. I'm really just curious to learn more.
A quick search shows that 9.4% of kids are diagnosed with ADHD.[1] (It's also the exact same percentage of total population with diabetes, which society seems to treat as an epidemic [2]) Of those kids, over 60% were on medication. Maybe I'm naive, but that seems like a lot. Do you think there are really that many kids who have "a debilitating condition"? The source lists a "behavior or conduct problem" as the number one reason to be diagnosed. That...seems a little suspect to me at first blush, but again, this isn't something I have much knowledge about.
