I agree with @DominicX, and think what @YARNLADY said is possibly very true. It seems Denmark is having some troubles with Muslim Arapb immigrants in their country who are not assimilating. Possibly Denmark is naive in the challenges that cone with immigration og very different cultures to their own? Or, possibly they are experiencing some of the pains most countries go through as new populations enter the country, I don’t have a grasp of whether it is really any different in how their country is adjusting, but I think it reinforces what many have stated that a small, homogenous, society in some ways is much easier. I heard that one reason Danes are so accepting of a very socialized system is because when the government is helping someone the individual citizens paying taxes can identify with the person receiving help, and so they have strong feeling of it could easily be me who needs the help, and they trust the person receiving help is not taking advantage of the system, because the system is felt to be there for everyone. In places like America people who in their own minds feel they don’t need any public assistance, many of them spend a lot time in their minds separating themselves from who they believe works the system. They do it by making assumptions about race, religion, ethnic background, the type of household they live in, intelligence, etc.
Many Danes in a show I once saw said part of the reason they feel happy is because they felt cared for and secure. I figure it has something to do with Maslow’s theory of self actualization.
And, back to possible naïveté about immigrating populations. I think the Danish are incredibly excepting and protective of their citizens. What we see in fairly recent history, specifically the holocaust, was that they resisted Hitler, and snuck almost all of their Jewish citizens out of the country into Sweden (Sweden gets credit to for accepting them). I give this example not to support naivitivty, but rather possibly dispelling that hypothesis and demonstrating that the Danish simply have a history of feeling united among their countrymen no matter what race or religion, and maybe their acceptance and attitude helps make it a happy place.
