Being on disability is depressing enough without having any one judge you for why you are on it. I know I've been through enough without having to worry what people are thinking about why I'm on it and that's why I don't tell anyone. Although I guess its not hard for them to figure out.
Working does give you a sense of worth, and I miss it. To integrate that into the programs for that reason makes sense. I know I miss the rewarding feeling after working.
