Sorry. I do not believe your number for Denmark poverty. There is a huge descrepency between 7.9% and 13.4%. 5.5 points. I am sure that we can realign the US numbers also -- with what recipe you are using. The stats are the stats. You condemned the US for the Poverty-Threshold and "insane crime rate". But you don't agree with the number for the Poverty-Threshold or Crime Rate for Denmark. Very convenient to adjust Denmark's stat -- but not adjust the US number too. MEH
".....1/6th (edit: actually 15.1%) of the US population lives below the poverty threshold. Maybe that is why the crime rate in the US is insane? "
Repeat: Denmark's "crime rate" and "poverty" are not sparkling, no matter how it is sliced and dice in stats.
ATM we have the problem that 25% of the prison inmates are from eastern Europe. I expect the government to deal with that issue pretty swiftly.
So, you agree that there is an issue in Denmark, right? I wish we could deal with things like this "pretty swiftly". Unfortunately, in the US, any attempt to deal with these same problems is seen as "bigotry" or "racism". Denmark is sitting in a "glass house" from what I can see.
Just be real, if you are going to continue with the Denmark-knows-best theme. 
I have nothing against Denmark, but you keep using it as a model that scales for the US.
As far as the other Nordic neighbors, choose one. I am learning a lot here. I like studying history and cultures. Very interesting.
I just finished listening to another of Thomas Sowell's book for the second time. I think anyone who likes history (economics, social, political) will enjoy it. (this is just a side-note)
Conquests And Cultures: An International History
BTW, you have ignored that Norway just had a 1-year anniversary for a 77 person massacre. Strong gun laws. Strong welfare system. Strong education system.
EDIT: frankly, this is one perfect example, where if people had weapons, they could have stopped the guy. Wide open space, and no one could stop him? For him, it was like shooting fish in a barrel. Too easy for the criminal.
