I'd be willing to bet that there's some percentage of people who don't have ADHD, but they're also not capable of adapting to and meeting the unnatural demands school and work place on everyone and so they struggle in those environments where most people don't. ADHD medication still helps them overcome that difficultly and those medications can make a huge positive impact on their lives as a result. I'm okay with that.

Maybe we should have a different diagnosis for those kinds of people entirely and leave ADHD to the folks who couldn't accomplish what they wanted to do even if they never had to work, go to school, or follow a schedule set by another person. In the end though, what you call it doesn't matter. Both situations are thankfully improved through the use of the same types of medications. Medications which are pretty safe and can mean the difference between being able to support yourself or failing to.

I'm okay with a wider spectrum of people falling under the ADHD umbrella even if some of them don't like being lumped in with people who really do have an executive function disorder. Odds are good those people wouldn't like whatever new label doctors came up with to describe them either. It'll pretty much always carry negative connotations because ultimately, it means that you don't have it in you to do what most people are able to do just fine.
