From Pope Benedict XVI’s encyclical Caritas in Veritate (2009):
Paul VI in Populorum Progressio called for the creation of a model of market economy capable of including within its range all peoples and not just the better off. He called for efforts to build a more human world for all, a world in which “all will be able to give and receive, without one group making progress at the expense of the other.”94 In this way he was applying on a global scale the insights and aspirations contained in Rerum Novarum, written when, as a result of the Industrial Revolution, the idea was first proposed — somewhat ahead of its time — that the civil order, for its self-regulation, also needed intervention from the State for purposes of redistribution. Not only is this vision threatened today by the way in which markets and societies are opening up, but it is evidently insufficient to satisfy the demands of a fully humane economy. What the Church’s social doctrine has always sustained, on the basis of its vision of man and society, is corroborated today by the dynamics of globalization.
When both the logic of the market and the logic of the State come to an agreement that each will continue to exercise a monopoly over its respective area of influence, in the long term much is lost: solidarity in relations between citizens, participation and adherence, actions of gratuitousness, all of which stand in contrast with giving in order to acquire (the logic of exchange) and giving through duty (the logic of public obligation, imposed by State law). In order to defeat underdevelopment, action is required not only on improving exchange-based transactions and implanting public welfare structures, but above all on gradually increasing openness, in a world context, to forms of economic activity marked by quotas of gratuitousness and communion. The exclusively binary model of market-plus-State is corrosive of society, while economic forms based on solidarity, which find their natural home in civil society without being restricted to it, build up society. The market of gratuitousness does not exist, and attitudes of gratuitousness cannot be established by law. Yet both the market and politics need individuals who are open to reciprocal gift.
