Those low numbers are likely because the wages in Norway are actually decent living wages.
Go figure, when people are well paid and living decent lives they are less prone to commit crimes.
I also find it funny that one of the "downsides" is that CEO's and other higher corporate positions can't earn as much as other places. There's and interesting correlation in there I think.
Someone else posted total inmate numbers from 2022 and it was less that 4,000. Out of 5.5 million people, that's doing really well compared to the U.S.
Here's a small comparison. Oklahoma has a population less than 5 million. Yet their prison inmate population is over 20 thousand. And if you look at all the states, it's a similar story. Especially in "red states".
