In his book, The Health Gap, Michael Marmot discusses the effect income inequality has on well-being and longevity. He discusses how the income gap is less in Scandinavia than almost anywhere else and shows how this translates into a narrower health gab between the upper and lower income brackets.
Finland is now starting “an experiment in the form of social welfare: universal basic income.” This holds promise to further narrow the health gap. The December 18th NY Times article about this does not mention “the social determinants of health” but some of what the article covers is straight out of Marmot’s book.
