It of course depends on the nature of the prison. I would claim it could be just like a regular apartment - except you can't leave. There is no reason for it to be doomy , gloomy and grimy if the raison detre is to protect the society from the person locked away.

I think norway's treatment of prisoners is great example of how to do this as sensibly as possible https://en.wikipedia.org/wiki/Life_imprisonment_in_Norway

Do you have any evidence that reality conforms to this theory?

Do you have any evidence that reality doesn't conform to this theory?

Not a counter-question just for the sake of counter-questioning; I am sincerely interested in knowing.

Then that's what should be fixed, isn't it? The amount should be substantial enough to a) be a significant deterrent for future screwups and b) support the former prisoner indefinitely.

That's a bill that probably won't get paid. What are they going to do, throw me in prison?

Possibly that's an appropriate punishment then, for the very worst of offenders.

I think above a few months, imprisonment probably isn't the answer. We should explore alternatives: corporal punishment (wouldn't you rather a single lash than a year in prison?), fines, slavery (why not make someone who commits manslaughter work for the victim's family for a decade, rather than sit in prison for a decade?) and, yes, execution (which is, I contend, more humane than long-term imprisonment).

I don't really know what the answer is, but I'm pretty certain it doesn't involve years of prison.

I think it literally is, which is why I think requiring it in order to graduate from high school or college is uncouth and unconstitutional (likewise, the draft).

I have no problem with it as a punishment for crime, although I do have concerns about the efficacy and efficiency of how it is administered. Does it make sense for someone with high-value skills to be cleaning toilets as community service?
