Whether you agree or not with how they got to prison has nothing to do with how a prison should operate. The point is prison's do what they do with people incarcerated and no one should consider it as a nice place to spend some time.
And yes, I'm all for taking the TVs out of prisons and not having it be a good time. I'm also against mandatory labor. They're prisoners, but they're still human beings.
Others here have said it's voluntary, so if that's true, that's at least better. I still think they should be paid fairly so as to not displace jobs from people not in prison, though.
It's clear though that I'm against this, and you're not, so there's really no point in continuing on. I'll just say that I hope you never have to experience working for pennies a day.
I'm more interested in prison for rehabilitation than I am as punishment. I'd rather we reduce the recidivism rate than bask in schadenfreude. I'm more interested in addressing why we have the highest per capita incarceration rate of any first world nation.
