Gulag is exactly what he described. And a suitable environment for those who truly deserve it. The concept of rehabilitation is fine...for those who were once suitable for public interaction. I know from familial experience that people do make mistakes...actually they fuck up. They do something stupid. They recognize what they did and don't want to go back to prison. These are not the habitual felons; not the sociopaths that fill our prisons. No weight piles, no air conditioning, no cable TV. Just hard work and an incentive to never return. For the incorrigible murdering rapists, child killers, cop murderers...they forfeit their "human rights" because they have demonstrated that they are not actually human. They are organic debris that needs to be removed. Lethal injection...with something that hurts like hell for an hour or ten, depending on the crime. Inject them, leave them locked in a dark, soundproof room in a straight jacket. Drag them out the next day and pressure wash the room. The true sociopaths won't be deterred, but a few of the "wanna be's" might be.
