You aren't tortured or starved. You aren't physically or psychologically abused. The food is hot and you are fed enough calories to not be hungry. You are given jobs to keep your mind busy, can shower, groom, and buy goodies with your work earnings.
If I had like 50 million stashed away and had to live like this for about 2 years in prison, then I could get out and enjoy my millions, sounds good to me... sign me up. White collar criminal judgments for corporations, high rolling individuals and politicians is a joke compared to the average joe.
