Nope, I'm not arguing that too much is spent on access for mobility. I'd just like the equivalent amount spent on the other equivalent disabilities. Trouble is, if there's only (say) £50k to go round, something has to give way.
As I say, there aren't any easy answers.
Wheelchair users who are employees don't have a statutory right to access every room in every building, no. As long as they can do their job in a safe way that respects their dignity and needs, then that is deemed to be OK. So, for example, my wheelchair-using friends have offices where one floor is adapted for them, which contains all they need for themselves and their work, and they can decree that people visit them rather than them have to go to visit the other people.
In a nursery, a workers who is a wheelchair user could ask that the ground floor be made fully accessible with the right loo and a small meeting room that offers privacy, and any activities involving his or her group of children could be organised around that space. If the building caught fire, then the knack would be to find alternative accessible accommodation using the insurer's monies, since the insurers would have to build in a clause saying they'd pay for equivalent access somewhere else for a while.
It doesn't have to mean that the wheelchair user is not able to work if they can't access every room or every floor.
Me and supermarkets...that's an essay in itself. OK, from first principles - I can't navigate traffic on foot safely because of the noise/fumes/feel of the tarmac under my feet etc. Can in a car, can't on foot. Weird but true. And I'm not allowed to park in the disability spaces as I'm not mobility-impaired enough. So I have to risk my life getting to the shop if I go alone.
Then I have to get past the doors that have a high pitched whining self-opening mechanism and a carpet pattern that stops my brain working and makes me feel sick.
Then I have to walk down the hallway with flickering overhead lighting that likewise cuts across my eyesight, whilst being jostled by the crowds, which hurts like hell thanks to skin sensitivity issues.
Then I have to go into the avalanche of smells (designed to tempt people to buy) and sights (likewise) and announcements and noise and chaos and they've moved lots of things (to keep people moving and interested, except it panics me totally), all whilst not colliding with people.
I end up not buying things because I can't talk at that point and can't get into aisles with overhead flickering lighting and can't figure out how to solve any of that because my brain just panics.
At the checkout, I have to try to handle conversation, unpacking, more conversation, flickering lights, beeping tills, opening bags (or having a conversation with a bag packer and them packing things in ways I can't handle due to OCD issues around food) and I drop the change everywhere and forget my PIN and act in a 'suspicious way' thanks to the body language issues that means I get tailed by security guards or stopped for Shopping Whilst Autistic
Then I've got to get me, my trolley, the shopping back across traffic without actually getting killed by a passing car or lorry
I can end up in tears in a corner, or 'shut down' completely and unable to fend for myself at all. It's so embarrassing, and then I have to go home and find I can't cook what I need because I've forgotten things in the panic or couldn't buy some things because of the access problems.
But it's all invisible disability. Staff in the shops are generally nice, but it'd be so much more dignified if they'd designed it to make it accessible for me, or had any autism training.
No wonder small children with autism sometimes fight as if their lives depend on it when taken into a supermarket. It's a bit like entering the front lines of World War 1.
