We could make it much cheaper, if we wanted to. Cages hold a man as well as cells made of bricks, prisoners can work whenever they are not sleeping and things like recreational facilities are just going be used for and by gangs.

We could make prisons much cheaper than they currently are just by choosing either rehabilitation or warehousing. Warehousing would be even cheaper - or maybe split the prisoners up by worth (essentially asking is this person a good person who did something bad, or a bad person) and then have two different criminal systems.
