Torben Andersen, an economics professor at Aarhus University, sees political unity as a factor in Denmark's narrow wealth gap.
"There are not the same strong conflicts and very strong parties and views like you will see, for instance, in U.S. politics," he said.
Some issues do tend to fan tensions in Denmark. One is immigration. With net immigration of about 2.25 people per 1,000 citizens, Denmark welcomes nearly as many as the United States. Many come from war-torn Middle East countries with few qualifications. Some of them struggle to find jobs, leaving some Danes to complain about immigrants benefiting from the welfare system without contributing to it.
Such anxieties have lent support to the anti-immigration Danish People's Party. Its influence has led to a tightening of immigration laws. It's become harder for foreigners to obtain residence permits and for refugees in Denmark to bring relatives into the country.
Despite the heavy tax burden, public support for the social security system remains high. In a Gallup poll published this month, 38 percent of people who were asked whether they were happy to pay their taxes said they "fully" agreed. Fifty percent "partly" agreed. A poll last year showed that 66 percent opposed cuts to the welfare system.
Kay Xander Mellish, a Wisconsin native who's lived in Denmark for 13 years, says one reason Denmark's system enjoys public support is that pretty much everyone, regardless of income, shares in its benefits.
"If you are a high earner in the U.S., you can pay a lot for social services that you will never use, and I can see why that upsets people," says Mellish, who's enjoyed a year's paid maternity leave and subsidized daycare. "At least when I pay for social services, I can see what I get back."
In Copenhagen, teacher Per Broenholt ticked off the government benefits he values. A father of two, he has six weeks' vacation a year, which he uses to visit a summer home or foreign destinations such as Thailand or Turkey. He cycles to work and uses the family car mainly to drive to the grocery store on weekends.
Still, he acknowledges, taxes are a burden. Income tax rates in Denmark range from 30 percent to 51.5 percent. There's little incentive to work toward a promotion, Broenholt says, because "the taxman would take half" the additional money earned. And gas is expensive, at around 12 kroner ($2.18) for a liter (0.3 gallon), a result of environmental taxes.
Advocates of low taxes, in the United States and elsewhere, have long argued that high taxes act as a drag on economies, stifling investment, hiring and spending. As with many countries with high taxes, Denmark's long-term growth has trailed the pace of expansion in the United States and some other major economies.
Among Danes, though, distaste for ostentatious wealth tends to outweigh dissatisfaction with taxes.
"Elite is a dirty word here," Mellish said. "The whole idea of ambition is embarrassing in Denmark. It's like being gay in the 1960's: Everybody knows it exists, but no one talks about it."
Wealthy Danes make up a lower proportion than in many other countries. About 0.3 percent of Danes earn more than $370,000 a year. In the United States, a full 1 percent had income over $394,000 in 2012, according to Internal Revenue Service data.
As the cost of their social welfare systems has grown, Denmark and other Nordic nations have embraced work incentives - a trend that's led to a slight widening in income disparities. Sweden has gradually cut income taxes for the employed by up to $330 a month. Denmark has pushed to lower the maximum period for full unemployment benefits from four years to two.
Prime Minister Thorning-Schmidt said she's committed to helping businesses stay competitive.
"We need to continue to take decisions to ensure that our model is sustainable and preserves prosperity," she said in an email to The Associated Press.
In the end, there's an economic trade-off, says Danske Bank's chief economist, Steen Bocian.
"You could probably have higher growth in Denmark, allowing for more income inequality," he said. "But it's a political question whether you would pursue that."
