The beds are cement slabs or metal racks with thin mattresses. Not most of them, most are like caged animals, waiting , pacing, praying to be called to work, or church or anywhere. But there are not enough jobs, not enough staff for work or church or recreation on too many days. Inmates must pay for their own shampoo, toothpaste, soap etc. Indigent inmates are supposed to be supplied limited quantities of these things, but they often go without.
Most inmates leave the table hungry.
In many states inmates are not paid at all for their work. In the states that do pay inmates for work the pay starts at .10 per hour. Things are not any cheaper in prison. Or any one of a hundred things along the same lines. Most people believe you must do something really violent to end up in prison.
