Sollicitudo Rei Socialis §17

¹⁷ However much society worldwide shows signs of fragmentation, expressed in the conventional names First, Second, Third and even Fourth World, their interdependence remains close. When this interdependence is separated from its ethical requirements, it has disastrous consequences for the weakest. Indeed, as a result of a sort of internal dynamic and under the impulse of mechanisms which can only be called perverse, this interdependence triggers negative effects even in the rich countries. It is precisely within these countries that one encounters, though on a lesser scale, the more specific manifestations of under development. Thus it should be obvious that development either becomes shared in common by every part of the world or it undergoes a process of regression even in zones marked by constant progress. This tells us a great deal about the nature of authentic development: either all the nations of the world participate, or it will not be true development. Among the specific signs of underdevelopment which increasingly affect the developed countries also, there are two in particular that reveal a tragic situation. The first is the housing crisis. During this International Year of the Home less proclaimed by the United Nations. attention is focused on the millions of human beings lacking adequate housing or with no housing at all, in order to awaken everyone's conscience and to find a solution to this serious problem with its negative consequences for the individual, the family and society. The lack of housing is being experienced universally and is due in large measure to the growing phenomenon of urbanization. Even the most highly developed peoples present the sad spectacle of individuals and families literally struggling to survive, without a roof over their heads or with a roof so inadequate as to constitute no roof at all. The lack of housing, an extremely serious problem in itself, should be seen as a sign and summing-up of a whole series of shortcomings: economic, social, cultural or simply human in nature. Given the extent of the problem, we should need little convincing of how far we are from an authentic development of peoples.
