If you are okay with waitstaff and prisoners being underpaid then you will be okay with others suffering the same fate.
A good percentage of waitpersons in the country are working below minimim wage so there is precedent for this type of carve-out to labor laws. Prisons are chock full of exploited workers with no labor rights. If the intellectually challenged are to be treated equally then they should have every right to be grossly exploited like the rest of them.
