it really depends on the type of disability...
i mean
it's pretty rare someone is *completely 100%* incapable of creating value for others.
generally its just a matter of not considering all the possible options.

True regarding the type of disability.
Regarding the second part I would say it is "pretty rare" that I see a successful business managed by a disabled human 🙈.
But with the original notes "not being able to socialize" in mind: lets say you are so lucky to be able to create value for others as a disabled human, then they still will not notice/find it, because of the missing social component. In what ever shape or form, it seems you most likely are depending on others if you are disabled 🤔.
