At Reader Supported News, Bernie Sanders notes that Denmark and the United States are very different countries, but insists that there are lessons the U.S. can learn from Denmark:

While it is difficult to become very rich in Denmark no one is allowed to be poor. Health care in Denmark is universal, free of charge and high quality. . . . They spend about 11 percent of their GDP on health care. We spend almost 18 percent. Danes understand that the first few years of a person's life are the most important in terms of intellectual and emotional development. . . [M]others get four weeks of paid leave before giving birth. They get another 14 weeks afterward. . . . [B]oth parents have the right to 32 more weeks of leave during the first nine years of a child's life. The state covers three-quarters of the cost of child care, more for lower-income workers. [V]irtually all higher education in Denmark is free. In Denmark, adequate leisure and family time are considered an important part of having a good life. Every worker in Denmark is entitled to five weeks of paid vacation plus 11 paid holidays. The United States is the only major country that does not guarantee its workers paid vacation time. The result is that fewer than half of lower-paid hourly wage workers in our country receive any paid vacation days.
