There are lots of ways to make prisoners happier during their time in prison. Provide places that one can ensure one's own health and safety, including private cells. Make sure folks have enough underwear and toiletries. Provide actual medical and psychiatric care. Provide well-balanced meals. Heck, we could easily make sure masturbation isn't against the rules. We could extend that stuff by doing things like paying the prisoners minimum wage. The money could be used to pay child support, debts, help support a spouse, pay for nicer toiletries, and so on. Or just saved up so that the person can actually afford to get on their feet after prison.
