It's frightening.
My dh gets dla, not changed over to pip yet, he works but can't work alone (we work together), he uses a wheelchair but that doesn't get rid of care needs, because he can't do anything without pain, having a wheelchair doesn't cure him and brings new care needs in many ways. If he had a kettle tipper, it wouldn't mean he could pour a drink without pain or risk of hurting himself (he's injured himself lifting up a carton of milk before).
Being able to do something within a reasonable length of time, without pain, and safely is nothing to do with using aids. The cost isn't straightforward either- paying a carer is one thing, but using a vehicle (cost of extra fuel) because you can't walk that far, higher cost of electricity for a electric wheelchair, or to heat the house when in all day...
It's not that simple. Disability related costs aren't always obvious.
Anyway, how many people really are able to do everything easily, without pain etc, with a perching stool and a kettle tipper and a microwave? It's laughable that it would be that easy (if it wasn't so scary that people actually believe it!)
It's all meaningless, aids don't remove disability, but what will happen is someone will decide a perching stool fixes everything and the most vulnerable people-who can't get help, who have no voice, who can't fight it, will suffer.
