I think there are two issues here:
Firstly, the idea that there is some binary distinction between ND and NT people has caused all sorts of havoc in terms of how people perceive their challenges. I can't tell you the amount of times that people have insisted that ND means that people's brains are 'wired' differently and that NT people can't understand the struggles of ND. It's all nonsense. Very few people have a completely NT brain. We all show variation and our brains will be structured differently to reflect lots of different personality traits such as kindness, extraversion or conscientiousness. Traits associated with ADHD and ASD are no different to this.
Many of us have ADHD and ASD traits and brains that reflect this. Somewhere along the line we draw a relatively diagnostic arbitrary line that separates those with sub clinical traits and those that can get a diagnosis. How you describe your traits, behaviour and the impact they have on your life will determine whether you're eligible for a diagnosis, not the actual differences in your brain. It's highly subjective and obviously open to intentional and unintentional manipulation. Some people will naturally underplay things and some overstate things.
We know for example that there is strong link between ADHD traits and Somatic Symptom Disorder so that patients with ADHD often overstate the impact of their ADHD on daily life. Research has shown that patients will report for example, intense brain fog when actually their cognitive functioning is only mildly impaired. They are more likely to perceive larger impacts because they are more introspective and hyper vigilant than the average person. It is complicated to untangle but ironically ADHD traits can lead to an overstating of ADHD symptoms.
Put simply, the brain is super complex and very few people are completely NT. Most of us will have undesirable traits that we need to manage and there is a tendency to overstate the impact of traits on our daily life. Instead of maintaing this ND and NT distinction, we need much more acceptance of the grey where most people sit. You will have challenges associated with ND traits that will make your life more difficult and expensive. This is normal. We should expect this in the same way we expect to get some physical health complaints over our lifetime. We must try to manage these as much as possible and not let them define us. ND has entered identify politics and we know how dangerous this is.
Secondly, in the context I outlined above, with the acceptance of everyone having ND traits and to some extent ND brains, we need to be careful about how benefits are allocated. The idea that the state can insulate you from the impact of your ND traits simply isn't realistic other than in extreme cases. We don't have the money, resource or desire as a population to do this so we need to be more honest about this. Yes, you might have ADHD and find life more difficult because of this. You might have subclinical traits that also make your life harder. To a certain extent this unfortunately is just the way it goes in the same way that I have to pay for glasses and contact lenses for my crap eyesight and pay to dye my hair because it's turning grey at a young age. I have to work really hard to not be overly agreeable and often get myself into difficult situations due to this trait. We are humans and complex beings.
ETA sorry the quoted post wasn't super relevant to what I needed up writing but can't remove it now.
