Well i have not seen any other threads on this topic but i will say i share your concern. I have 5 adult kids, likely all on the spectrum somewhere but only one is 'disabled' with autism. He has a learning difficulty too, receives pip full award both elements and is in the UC group where he doesn't need to look for work.
He is in some supported paid employment one day a week and voluntary employment 3 days a week (cafes)
He was assessed by 2 psychiatrists as requiring supported living but social work say he doesn't qualify as they are only allocating that to people with night needs in our area. So he is still at home with us.
My other DC are cognitively able. That is what makes the difference for them - they have had difficulties during high school but, once away from that situation, they have been able to find employment that does not pressure them.
My DS1 started with a lot of night shift work where he worked alone and that suited him.
My DD1 is self employed and works from (her own) home and that suits her
DS3 is very good with computers and very bright so he is fine there
And DD2 struggled in high school but has recently left and seems to be settling well in a much smaller group at college.
So - there's only the one of mine that comes into the category of actually requiring support from the state - and he does put in a fair few voluntary hours helping the community.
He really will need life long support - he is very different from my others due to his cognitive problems. Whereas my others, they definitely do have the ability to make a living and do not need help with cooking, budgeting, hygiene etc.
My concern is that some of those that are struggling and now getting diagnosed later in life because they have developed debilitating mental health problems would actually manage in a lower pressured job with a slower pace and fewer demands. So, to my mind, there is a difference between having autism and having autism to a disabling degree.
Same with adhd - there's debilitating adhd which causes sufferers to gamble away all their cash, be a danger on the roads, not be able to hold down any job, take very risky and impulsive decisions. And there's adhd where concentration to a task is very difficult, you are impulsive but not dangerous.
In a nutshell, i am wondering if many of these recent successful claims are actually not because the primary diagnosis (autism/adhd) is causing a disability - but the secondary effect of MH problems which might not have occured with different life choices.
And - yes - if the money runs out, my disabled DS is absolutely incapable of making a living in any field and that does concern me.
