where you could hire anyone from students, to sex-offender ex-Cons, to the mentally impaired ...

Are you suggesting forced labor camps even for mental patients and other disadvantaged groups in society?

A lot of mentally impaired people are eager for a chance to have work they can handle...along with its associated benefits (something to do, earning money...)

Not all mentally impaired people; there is of course a spectrum.
