You're correct that most of these are asking for prison to be a more tolerable place to live. Making prison a rough experience should encourage inmates to avoid crimes which will send them back. The article's author contends that the current conditions in the prison where he serves his time re-enforce criminal behavior and empowers "gang recruiters, extortion, and other threats" by depriving prisoners. He has the advantage of seeing what happens each day, but has a sample-size issue in that he's only experienced a small number of prisons. I would be interested in seeing his proposals tested in a controlled studies. None of them seems difficult or expensive to implement.
