Actually supporting differently abled people means letting them pursue the professions they find rewarding. Deaf people in "The Country of Equality" obviously had no one truly advocating on their behalf, since no one bothered to ask them why they worked at the factory. The society simply assumed that they must be forced to work there, because obviously Deaf people wouldn't have agency, right?
True equality means recognizing everyone's humanity. It means seeing them for who they really are, not just what we imagine them to be.
