You are still entitled to benefits as a single adult if you live with a parent who works.
Yes you are but some people can't easily manage the requirements of maintaining a benefit claim so don't bother - or their relatives don't bother on their behalf - because they don't need housing costs covered and they have their PIP. The man who the Telegraph column was about being an example.
I grouped parents and spouses in together for ease but you're correct the reason why such a disabled person might not claim ESA or UC in those circumstances does differ.
If you have a working spouse it is presumed that you share income. I know this as I previously lives with someone who was unable to work and I know what he was receiving before he met me, during and afterwards. Nobody is expecting unpaid carers to do this work, the services are there, use them. At least then the government will get a realistic picture of the demand. You seem to think I’m fighting against you, I’m really not.
Yes, I'm aware. But the working spouse in that scenario often has a lot on their plate and probably no energy left for complicated expense-based monthly systems of submitting and justifying everything.
We got into this because you were insisting that people who claim PIP and can't work would also be claiming ESA, which would passport them through to assistance with the admin. They don't necessarily, so they aren't and they won't.
I'm arguing with you at length because you're defending - at length - a right wing proposal borne out of unpleasant beliefs about disabled people. A proposal that would make the lives of disabled people significantly harder if implemented, and also a proposal designed to cut benefits spending on disabled people.
Given some of the other things you've said, it's unaccountable to me that you're so keen to be an apologist for this horrible idea, but apparently you are .
