Let me first start off by saying the prison system here in the US is a wreck. It really serves zero purpose beyond housing those who have broke the law.
The following article however does shed some light on going from one extreme to the other.

Norwegian mass murderer Anders Behring Breivik told a panel of judges Thursday that his solitary confinement in prison had deeply damaged him and made him even more radical in his neo-Nazi beliefs.
Dressed in a black suit, the right-wing extremist who killed 77 people in a 2011 bomb attack and shooting spoke coherently and without emotion as he addressed the panel considering if his isolation is inhumane.
"I have been damaged by the isolation ... (and) radicalization has been a consequence of it," a stone-faced Breivik said. "I have not been a little hurt, I have been very damaged."I'm all for rehabilitation, except in the most egregious cases (and he certainly counts as one), but reading the red part just makes me shake my head.Sejersted said Breivik lives in conditions that are better than the ones for many other inmates. In compensation for his solitary confinement, he has a three-cell complex where he plays video games, watches TV and exercises. Breivik also is served coffee and newspapers in the morning.
On one extreme you have the US Prison System, then on the polar opposite spectrum, a mass murderer (who I believe can never be rehabilitated) lives in what amounts to a private apartment hes just not allowed to leave.
You are welcome to hop on Google for other images for what his "living conditions" are like. He literally lives better than most homeless people is my guess.
