I've worked under communist regime. A real one, a few decades ago, and let me tell you, they also demanded proof of disability. Did you have different experience?
I wasn't trying to claim that only capitalists dehumanize people. But that's what we mostly see today because that's the majority of our society.
When it comes to the types of disabilities that are being discussed in this thread and that I was referring to - to say varied types of autism - I doubt any type of organisation that treats employees as "resources" will work in a decent way.
