Well aren't you just delightful? I'd just LOVE to have you as a friend, so supportive and encouraging... not.
Is it so difficult to understand that people have different strengths and skills? Some are super organised without even trying, and others can struggle to organise their way out of a paper bag. Or that some children are easier to raise than others, or that some people have more complicated lives, with extended family commitments, demanding jobs, their own or other's physical or mental illnesses.
No, no, we're just whinging, lazy people..... because if YOU with your one child with no particular additional needs can manage it just fine then everyone else is clearly just incompetent.
I mean I'm organised just fine, with 2 brilliant boys who I have taught to keep a track of their schedules by updating in the family calendar, I loathe online shopping so go in person, I have a mother with chronic illness who I help care for, I have a sister who I've helped gain employment and supported through mental health issues, I have a self centred, self pitying ex who I do my best to protect my boys from, I have a demanding job that I occasionally struggle with, oh yes and I have ADHD too.
But that's because I've been blessed with some strong fucking resilience and I also have the empathy and compassion to recognise that I have been blessed with this and that not everyone else has. Qualities that you seem to be severely lacking.
