The sanitoriums were closed for good reason. Bad as homelessness is, it is better than the abuse of sanitoriums.
Not a sanitorium, but i know someone who was in an orphanage, they beat kids with a metal chimney brush if they put their head on the pillow when they slept. This earned them lots of awards for how nice all the kids beds were. Sanitoriums were reportable just as bad, but I don't have such close accounts.
