Pope John XXIII
Mater et Magistra §33
Mater et Magistra: On Christianity and Social Progress
33 Of special doctrinal and practical importance is his affirmation that "if the social and individual character of work be overlooked, it can be neither justly valued nor equitably recompensed." (12) In determining wages, therefore, justice demands that account be taken not only of the needs of the individual workers and their families, but also of the financial state of the business concern for which they work and of "the economic welfare of the whole people." (13)
