Listen and Learn
As Jeff Smith states, there are lessons to be learned. While the terminology is not the same, the concepts are.

A&E has a show called "Scared Straight" which brings youth into the prisions to scare them out of getting in trouble. While I hope some youth get scared, in reality, I am not sure if others get anything out of it.
Along those lines, learning from the prisoners could be an interesting approach to business.
How do they approach finance? How do they deal with staffing/resource challenges?
