Medical Care as a Luxury Good

For our ancestors, long-term allegiance signals included weddings, funerals, helping to build homes, war and revenge killings, and care for the sick and injured. We have lost many old signals to alternative processes, however, and it seems difficult to create new signals. Thus great weight is placed on caring for the sick and injured as a signal of social allegiance; maybe we induce medical care not so much to make people healthy, but mainly just to show that we care.
