Swedes, usually perceived in Europe as a comfortable, middle class lot, are poorer than African Americans, the most economically-deprived group in the United States
"Black people, who have the lowest income in the United States, now have a higher standard of living than an ordinary Swedish household," the HUI economists said.
If Sweden were a U.S. state, it would be the poorest, measured by household gross income before taxes, [the report authors]said.
One thing this article you shared does not mention is this — SWEDES ARE RELATIVELY A HOMOGENEOUS PEOPLE ( WHITE ). They share a culture which is historically informed by Lutheran values.
I will concede that this culture is slowly ebbing away (immigration from Muslim countries being a factor ) and Lutheran values are slowly being replaced by secular ones, but by and large, they are still relatively intact.
So, inspite of the fact that they do not make as much as blacks in the USA, THEY DO NOT HAVE THE SAME CRIME RATES AS BLACKS. At least not yet.
