Centesimus Annus §34

³⁴ It would appear that, on the level of individual nations and of international relations, the free market is the most efficient instrument for utilizing resources and effectively responding to needs. But this is true only for those needs which are "solvent", insofar as they are endowed with purchasing power, and for those resources which are "marketable", insofar as they are capable of obtaining a satisfactory price. But there are many human needs which find no place on the market. It is a strict duty of justice and truth not to allow fundamental human needs to remain unsatisfied, and not to allow those burdened by such needs to perish. It is also necessary to help these needy people to acquire expertise, to enter the circle of exchange, and to develop their skills in order to make the best use of their capacities and resources. Even prior to the logic of a fair exchange of goods and the forms of justice appropriate to it, there exists something which is due to man because he is man, by reason of his lofty dignity. Inseparable from that required "something" is the possibility to survive and, at the same time, to make an active contribution to the common good of humanity. In Third World contexts, certain objectives stated by Rerum novarum remain valid, and, in some cases, still constitute a goal yet to be reached, if man's work and his very being are not to be reduced to the level of a mere commodity. These objectives include a sufficient wage for the support of the family, social insurance for old age and unemployment, and adequate protection for the conditions of employment.
