As a preface, just so you don't think I don't understand what you're talking about—my dad struggled to hold down a job for most of my childhood and finally got diagnosed with ADHD and started medication after he turned 50. I'm intimately familiar with the impairments that ADHD can cause and the real harm that is possible.
That, said, what you're describing is exactly the kind of modern overhead that I'm talking about—the modern world imposes a million little things to keep track of that ultimately shouldn't be required, which leaves us chronically falling behind on menial tasks. That leads to anxiety and depression that makes things even worse.
In the present reality, medication may be an appropriate patch to quickly restore sanity to people who need it, but I'm unconvinced that we should treat medicating a full 5% of the population for ADHD as a reasonable end goal. There are huge social movements for making accommodations for a portion of the population much smaller than that. There's no reason we can't make substantial changes to accommodate ADHD, especially given that said accommodations would really benefit everyone.
I've got no problem with the OXO Good Grips argument ("accommodations help everyone"). The only thing I'll take issue with is laying the blame at the feet of the modern world, because I know I'd be just as much of a flake if I lived in a village of 75 people and grew turnips for a living.
My psychiatrist recommended Gabor Maté for what it's worth, but I prefer a really reductionist "it's all about dopamine" model. It might be simplistic, but it has the advantage of being concrete.
