When one says prison there are so many levels or variants, just like Martial Arts training: Low Security environments/Resident Halfway Houses The County Jails, or “Houses of Correction” for misdemeanors & low-grade felons Medium to Maximum Security State Prisons & Penitentiaries The Federal low security camps - “Club Feds” for white-collar criminals All other Federal Prisons up to “Super Max” in Colorado Having been around, my two cents is I think the “Prison Rehabilitation Movement” which really blossomed during the 1960s is one of the great scams of the 20th century, not up there with the Ponzi Scheme called Social Security - but close. At best, IMHO for those who will be on the outside shortly offering two “support programs” during incarceration that should focus on correcting two issues that are directly tied to why many of these people are in prison in the first place may be cost effective: 1) Offer to teach the inmates how to read & write at the high school level since so many inmates have almost no significant educational background. I am not talking “offsite college degrees programs” but correcting how many of them are functionally illiterate or worse. 2) Any reasonable therapies for them to address their alcohol and drug abuse problems. This is why so many of them are there in the first place. They are not just problem drinkers, but violent problem drinkers who also abuse a potpourri of prescription and illegal drugs. One cannot hold any type of stable employment on the outside with the frequent benders these guys (& girls) typically go on. Short of that - lock ‘em up and any work details and/or light industry programs that help reduce the taxpayer’s cost are as a rule are a good thing. Just remove the Cable TV, or their weight gyms and squash courts. Keep on saying, “Incarceration is Punishment” and make it so every day. BTW everyone talks about the costs of incarceration. Has anyone done a comparison what a “career criminal” can cost society when they are on their crimes sprees amongst us law-abiding productive type citizens between jail stints?
