This chapter is devoted to evaluating the relationship between material Well-being and the rest of life — i.e., human Well-being. The concept of material Well-being is only an abstraction, and it only covers one aspect of human life; we must be careful not to misuse it, or place more importance on it than is warranted. In fact, only weak relations can be discerned between measures of material Well-being and three other aspects of life: happiness, health, and social participation. This is good news, since dominance of all of life by one type of good (wealth) or one type of distribution system (the market) would be unjust and undesirable.
