Does your comment imply that I am racist? What my comment recognizes is that people of different cultures have different worldviews and behaviors which sometimes clash; that some individuals will exhibit racist behaviors because of this; that there is greater variance in economic well being; that some will choose crime as a way to improve their lot; that some will form violent gangs which include only those of their own ethnic background. All of this happens much less in a culturally and ethnically non-diverse country such as Norway or Japan. But now that they have more muslims, they are dealing with more crime. That is no surprise.

It is not cheaper for Norway to house prisoners per capita, quite the contrary. But Norway is a welfare state. Free or not, the state pays a lot for each person to live, so relatively speaking, the difference is not as great as in the U.S. But taxes in Norway are 2.25 times the overall rates in the U.S. Reality is that their system won't work here.
