The development of economic activity and growth in production are meant to provide for the needs of human beings. Economic life is not meant solely to multiply goods produced and increase profit or power; it is ordered first of all to the service of persons, of the whole man, and of the entire human community. Economic activity, conducted according to its own proper methods, is to be exercised within the limits of the moral order, in keeping with social justice so as to correspond to God's plan for man.
