Somewhere, they reserve massage as a career for blind people so they will be employable. There are blind developers and I co-own a not active group for such that was begun because some of the tools developers need aren't very blind-friendly.
We absolutely could do a better job of helping people with various impairments make their lives work. Up to 60 percent of people have some degree of impairment but only about 15 or 20 percent self-identify as disabled. The people who are less impaired and are able to make their lives work without much accommodation tend to hide it or at least downplay it and don't call it a disability.
He is absolutely correct that impaired people are impaired at least as much by social climate shaping expectations as by the physical limitation itself. Many things can be accommodated fairly readily in logistical terms IF you can just get people on board with doing what's necessary.
