ADHD behavior is normal human behavior, because we're all human.
And indeed, some quite reasonable accommodations and changes in the way the society functions and forms expectations of ourselves and others would go a long way towards making ADHD folks living fulfilling lives without pain.
All that said, executive dysfunction is still a thing, and ADHD folks routinely find themselves struggling with their own goals and lives, apart from the society and its expectations.
Technology can and does help a lot (electric kettles that turn themselves off, washer-dryer combo machines that don't require remembering to take clothes out, etc).
But then there are still things that I struggle with on my own, like wanting to send postcards to friends and taking literal years to get to it.
I really can't blame it on the society.
That's where the meds can make a big difference in one's life.
In some ways, ADHD is an advantage. We fare better than others in emergencies. Hyperfocus is an asset. Having a million hobbies is a plus.
But in other ways, it's something that makes us need support.
The meds are one of the ways the society accommodates us and gives us that support.
