Gaudium et Spes gets a bit more specific on guidelines for international economic policy …
The following norms seem useful for such cooperation:
a) Developing nations should take great pains to seek as the object for progress to express and secure the total human fulfillment of their citizens. They should bear in mind that progress arises and grows above all out of the labor and genius of the nations themselves because it has to be based, not only on foreign aid, but especially on the full utilization of their own resources, and on the development of their own culture and traditions. Those who exert the greatest influence on others should be outstanding in this respect.
Of those who have much, more is expected, or something like that …
b) On the other hand, it is a very important duty of the advanced nations to help the developing nations in discharging their above-mentioned responsibilities. They should therefore gladly carry out on their own home front those spiritual and material readjustments that are required for the realization of this universal cooperation.
Consequently, in business dealings with weaker and poorer nations, they should be careful to respect their profit, for these countries need the income they receive on the sale of their homemade products to support themselves.
If Third World nations have nothing in terms of competition to give multi-nationals, one would expect this is a given. Too bad that obsession with total competition has sullied capitalism.
c) It is the role of the international community to coordinate and promote development, but in such a way that the resources earmarked for this purpose will be allocated as effectively as possible, and with complete equity. It is likewise this community’s duty, with due regard for the principle of subsidiarity, so to regulate economic relations throughout the world that these will be carried out in accordance with the norms of justice.
Suitable organizations should be set up to foster and regulate international business affairs, particularly with the underdeveloped countries, and to compensate for losses resulting from an excessive inequality of power among the various nations. This type of organization, in unison with technical cultural and financial aid, should provide the help which developing nations need so that they can advantageously pursue their own economic advancement.
d) In many cases there is an urgent need to revamp economic and social structures. But one must guard against proposals of technical solutions that are untimely. This is particularly true of those solutions providing (people) with material conveniences, but nevertheless contrary to (a) spiritual nature and advancement. For “not by bread alone (do we) live, but by every word which proceeds from the mouth of God” (Matt. 4:4). Every sector of the family of (humankind) carries within itself and in its best traditions some portion of the spiritual treasure entrusted by God to humanity, even though many may not be aware of the source from which it comes.
A “spiritual treasure” as part of an original grace from God.
