Why should X% of people be on social programs if 75% of them can type a number from the parsley tag into the computer (or scan the tag on the parsley)? Isn't it a more dignified life to have a purpose of helping your fellow humans select and pay for their groceries than to sit around being paid by a social program because we didn't want to make cashiers' jobs more automated? I think for those people lowering the bar is helpful to their psyche.
(I had a family member, since passed, who was significantly mentally handicapped by a difficult birth sequence. She loved nothing more than to feel like she was included and being helpful to the limits of her ability.)
