From Pope Benedict XVI’s encyclical Caritas in Veritate (2009):
T he principle of subsidiarity must remain closely linked to the principle of solidarity and vice versa, since the former without the latter gives way to social privatism, while the latter without the former gives way to paternalist social assistance that is demeaning to those in need. This general rule must also be taken broadly into consideration when addressing issues concerning international development aid. Such aid, whatever the donors’ intentions, can sometimes lock people into a state of dependence and even foster situations of localized oppression and exploitation in the receiving country. Economic aid, in order to be true to its purpose, must not pursue secondary objectives. It must be distributed with the involvement not only of the governments of receiving countries, but also local economic agents and the bearers of culture within civil society, including local Churches. Aid programmes must increasingly acquire the characteristics of participation and completion from the grass roots. Indeed, the most valuable resources in countries receiving development aid are human resources: herein lies the real capital that needs to accumulate in order to guarantee a truly autonomous future for the poorest countries. It should also be remembered that, in the economic sphere, the principal form of assistance needed by developing countries is that of allowing and encouraging the gradual penetration of their products into international markets, thus making it possible for these countries to participate fully in international economic life. Too often in the past, aid has served to create only fringe markets for the products of these donor countries. This was often due to a lack of genuine demand for the products in question: it is therefore necessary to help such countries improve their products and adapt them more effectively to existing demand. Furthermore, there are those who fear the effects of competition through the importation of products — normally agricultural products — from economically poor countries. Nevertheless, it should be remembered that for such countries, the possibility of marketing their products is very often what guarantees their survival in both the short and long term. Just and equitable international trade in agricultural goods can be beneficial to everyone, both to suppliers and to customers. For this reason, not only is commercial orientation needed for production of this kind, but also the establishment of international trade regulations to support it and stronger financing for development in order to increase the productivity of these economies.
