Author makes some big claims without much evidence. The poor conditions of US prisons, and lack of focus on rehabilitation is I think pretty well known for anyone who cares, along with the opposite reality for Nordic prisons.

But you can't just throw your hands up and say, "money! corruption! racism!" and completely ignore that the American people asked for this system in response to rising crime waves. No matter how little corruption you get the American people as their thoughts stand today will never adopt the Nordic system.
