The Nordic model has also been positively received by various social scientists and economists. American professor of sociology and political science Lane Kenworthy advocates for the United States to make a gradual transition toward a social democracy similar to those of the Nordic countries, defining social democracy as such: "The idea behind social democracy was to make capitalism better. There is disagreement about how exactly to do that, and others might think the proposals in my book aren't true social democracy. But I think of it as a commitment to use government to make life better for people in a capitalist economy. To a large extent, that consists of using public insurance programs—government transfers and services".
