That's correct, for one thing most of the prisoners in Norway are Norwegians Just like the Swedes in Sweden and the Japanese in Japan. Many countries are much smaller than the US and of one ethnic group which makes it a lot easier to be on the same level. Most countries with one ethnic group have better graduation rates and people that care about what happens and have pride in their country. The US is quite large and consequently of many ethnic groups and many have come from the countries that don't have problems, so what has happened when it all comes together. People just don't understand each other and probably never will. No other country has had the history of the US and the diversification of the DNA's which in essence boils down to the root cause along with wrongs done many years ago. Also just look at today's politics if one wants to see just how different this country thinks and the difference of thinking from the cities to the urban
and the religions. It's a mess.
