So you're saying the child molesting mother raping murdering Norweigians are treated kindly for their crimes, and come out the other end a welcome member of society after a few years at the penal country club?
And please don't tell me Norway has no such humans. That's like claiming there are no gay men in the NFL. Some statistics are essentially impossible.
He's saying nothing of the sort, in fact he doesn't mention it at all, and of course we have. We also have high-security prisons. I appreciate your true statement about reform ("The Incarcerated States of America" makes me chuckle), but I'll mention a couple of examples:
For instance we have one of the worst mass murderers in history, Anders Behring Breivik, effectively in isolation (mostly for his own safety from other inmates). He's sentenced to something which translates to something like "Containment". In his case it's a high-security prison sentence initially for 21 years, but it can be extended indefinitely based on evaluation of his danger to society. As he's reportedly still showing no remorse or will to change his extremist views he may very well be imprisoned for the rest of his natural life, in fact it's what I and most people I have discussed it with believe will happen. This type of sentence will invariably be used when the courts deems the perpetrator to be a substantial danger to society.
In a gruesome year 2000 rape and murder of two young girls (The "Baneheia murders") one of the sentenced perpetrators was released on parole in 2016, and has been living with a secret identity under close scrutiny until fully released in 2019. He's served his sentence and has been evaluated by experts who deemed him no longer dangerous. Doing anything other than releasing him would not be justice. In prison he received training as a baker, and presumably he's being a more or less productive member of society, although the public knows nothing about his whereabouts or details of his life. He certainly wouldn't be welcomed by a lot of people if they knew of his crimes (I myself would intuitively trust him a lot less with my kids than I would most others), but he's served his sentence and has a right to carry on with his life.
So our penal system can handle the hard cases, while being very successful with reinstating people convicted for less serious crimes into society. Such success is also quite common for the more serious cases, as we also have a support system for people recently released from prison. Unless, of course, you define "successful" punishment by how close it is to "An eye for an eye, and a tooth for a tooth", but in that case you're talking about a religious revenge concept belonging in the dark ages.
I think the US could do a lot worse than looking to Scandinavian penal systems for inspiration. As far as I know it's by no means certain that harsher punishments, even the death penalty, has a higher deterring effect *at all* for some serious types of crime. This goes for less serious crimes as well, although too lenient punishments will fail to deter would-be criminals.
