By most measures, the Nordic countries regularly rank among the best in terms of equality and business friendliness. Political scientist Carsten Jensen delves into what is exceptional about equality in the region, and outlines "the four equalities" that set it apart: economic, intergenerational, gender, and health. The four types of equality have their origins in unique political compromises made in the twentieth century. The resulting social market economies of these countries affect their growth and levels of equality even today.
