The healthiest societies appear to be those of the Scandinavian nations, such as Iceland, Denmark, Sweden, Norway and Finland, which tax the wealthy rather heavily, but which provide adequate subsidies so that no one suffers hunger, death and illness from a lack of adequate medical treatment or poor housing. Observe that none of these nations is particularly rich in natural resources, certainly not as rich as the US is, and that the average Icelander, Norsky, Dane, Swede and Finn lives a middle class existence with affordable education, medical and housing for all.
The poorest are the Iraqis, Bosnians and such that have arrived in these countries more recently.
