Incredible. Almost all of the money saved could be either returned to the taxpayer, or used to build houses for the poor on the 127 prison sites.
And if reducing costs is your only goal. Well there are other options to get rid of criminals..
Or you could just them as free labor to build those house for the poor.
Better example would be Norway or Netherlands: more expensive prisons, but least prisoners per capita: https://www.dutchnews.nl/news/2014/04/the_netherlands_has_ex...
The point of prison system should be rehabilitation not keeping prisoners down for life.
