Pensions, Population, and Prosperity
It is a universal fact of human experience that the interaction between generations is at once a source of material and spiritual support, social development, and tension (if not conflict). It follows that it is a perennial challenge to minimize the negative potential and maximize the positive potential of this interaction.
Concern over the relationship between young and old spikes from time to time according to the rise and fall of sundry political or cultural crises. That concern is sometimes based on real, significant problems, and sometimes it is based merely on the perception that one or the other side of a generational battle has lost touch or has failed to assimilate the knowledge or habits necessary for the maintenance of advanced civilization.
