I think he means that, if prison hurts a bit, so what, it’s prison.
Can you make an argument for why prison should not hurt at all? Feel free to define “hurt.”
Because America is a brutal society uninterested in progress or decency. Just look at the per capita incarceration rate and the number of likely innocent executed people.
Prison is a punishment. Punishments are supposed to hurt. It may not be a physical pain but it also shouldn’t be a good time.
Apparently there's a fine line between slavery and "not having a good time"...
This is the first I’ve heard of this line. Where is it exactly?
Well, in my opinion, 1) you have to feed yourself in real life, you should pull your weight in prison too, and 2) the whole reason you're there is that you did something presumably wrong, and the consequences for that have to suck if they're going to motivate you to not do it anymore.
