I've mentioned it before somewhere, but what we are seeing currently is culturally just so different to other parts of the world. I take Japan as my example. Their work culture is extreme in many respects, but so much of it is driven by an attitude of wanting to contribute to the society people live in.
It means that opportunities are sought for people with all sorts of disabilities to contribute and work. The robot cafes are an example of allowing people with extreme physical disabilities still see a purpose in their lives, and to interact with people in a way they normally wouldn't.
When I mentioned this before, I got shot down, saying that we shouldn't force disabled people to do any work they theoretically could, but I still see it from a different perspective. I wouldn't want to live my life out doing nothing much if I had an accident tomorrow which almost fully paralysed me.
And similar can be said for people with mental disabilities or ill mental health. One company I worked with (a funeral one) employed a person with Downs syndrome as a bearer. The person worked part-time and they weren't mentally able to hold much of a conversation beyond some basics, but they did a fantastic job at the physical aspects of funeral work.
We know working (albeit in the right kind of job) has a positive effect on mental health, if only because it allows for interaction with other people.
What Rishi is doing is trying to run before he can walk. As another poster pointed out, in many ways we don't have the infrastructure to support many people into work and we'd need heavy investment before any of this could become a normal expectation for people to look for work they can do.
But I do agree that we, as a society, are too quick to label people as unable to do anything. In a way, it infantilises and victimises people who might otherwise benefit.
