Abstract
Problems of distributive justice throughout the lifespan are not new. Yet, the increased aging rate of contemporary societies and an array of new life‐extending technologies (LETs) make these problems more and more urgent and complicated. This chapter analyzes the moral and political impact of the LET. There are three kinds of “intergenerational” justice: justice between non‐coexisting generations, justice between partially co‐existing generations, and justice between coexisting generations. The advantage of considering LETs in the light of justice between age groups is that we can assume a complete‐life view. LETs significantly modify the duration and the features of each stage of life. A consideration of the specific needs and features of each stage of life in a lifespan‐enhanced society is needed to regulate policies and offer fair equality of opportunity to each age group.
