Social structuring IMO. It's common and gets many in the end.
Here, it's an increasing attitude in society that disabled and older people are of little use, and a burden on society, unless they are paying other able people for their care, therefore don't need whatever they have.
Therefore everyone and anyone has rights over them and what they have, and to make money from them, as long as it's wrapped up as 'concern.'
Some of it is control, some greed, and some of it criminality, but it all makes assumptions over rights to autonomy.
I raise disability, because it's where it starts with ageing.
Lesser abilities = needs help. Needs help = burden. Burden = reasonable target.
Even fit older people start to show frailties of age, and it's what makes them 'other' and seen as no longer entitled to all sorts of things, and others entitled to whatever they have and to take over, needed or not.
Both disabled and older people used to have their place and uses in society, but that's been pretty much eradicated, and current financial contribution is all that's valued now.
Many wont agree or that it's been encouraged by governments, because it's too uncomfortable. But ask the physically disabled their experiences of denied autonomy through disability, and how it significantly ramps up and doubles as they age, while they're still working and long before they're officially elderly. They get targeted early, and often more frequently the older they get.
Everyone with the smallest grudge will report to the DVLA, as 'shouldn't be driving' the DWP because 'shouldn't be working/ shouldn't be assisted to work/ might be somehow committing fraud', housing, because 'someone else could use that flat', council as needing social service assessment because 'wont employ dodgy neighbors lad to do gardening/wash car' and 'obviously in need of help and could pay for someone else to do it.'
Reporting for supposed 'dementia' usually happens when they realize they've been seen through/nothing else has worked.
It varies from downright attempted defrauding by the criminally minded, to ideas
of 'they don't need and I/we could use it' / 'they'll be dead soon' backed up by the constant nudging towards needing paid for dependence on others, being expected to put others needs automatically first, ('you've had your life/help') forced DNR's, and encouragement towards assisted suicide all in the name of ' the greater good.'
Disabled people's two tier society experience, is actually the writing on the wall for what starts to happen to many people as they age, but denial is so strong, it comes as a shock to realize it's the future for many previously non disabled too.
The modern climate of automatic othering of physical vulnerability and current ability to financially contribute, affects everyone's social 'status' negatively as they age, allowing nefarious relatives and criminals to predate more easily imo.
