Wealth is well-being. And well-being, for a mature human being, is the assurance of relationships that nourish you, the assurance of a future that is relatively secure, that is somehow protected against appalling disaster and deprivation. Wealth is the capacity to put down roots where you are and be at home with yourself and your neighbors.
If you understand wealth in those terms, then wealth ceases to be about endless material growth and becomes very much about how you create the kind of social cohesiveness and trustfulness that keeps societies going.
