For quite a few disabilities it's the energy cost of doing several things that mounts up rather than any one element.
Eg I have ME/CFS.
I can't get public transport to meet people. I could get the bus to sit alone in a park, or I could get a lift to meet people, but both is too much and could mean a week in bed.
I can work, but only for a few hours and not every day as I need time to recover the energy cost of working.
On the days I work I cannot also do any of the other things I manage on home days. I cannot prepare meals, have a wash, clean the house, do shopping etc because I have used all my energy working.
I have a blue badge, which means DH can park closer to things so I can participate in activities more.
With the correct support, many disabled people can participate in a range of work and social activities, but govt has decided that because some disabled people can do a few things sometimes they can do all the things all the time. This is almost never the case in reality.
Giving people support and opportunities to work as and when they are able, and help when they are too unwell to work, is more effective than removing support and forcing people to work their way out of poverty despite unsupported disability.
There are ways to get more disabled people into various workplaces, but they require money, thought, and bespoke solutions. Govt is offering none of these and just wants to reduce the bill.
