There is a more complex breakdown that what you suggest: "For the public, it's not a hardship, but rather, an investment."
For some of the prisoners, for some of the public, its an investment. For some of this same public, some of the other prisoners, it is a hardship. For some other part of the public, the breakdown is different.
The prison issue should eventually come into focus as the complex problem it is. Up to now its not talked about enough for most (including myself) to have a clear opinion.
