The encyclical letter Laudato Si is available here on the Vatican website. More of the narrative of the widespread lack of dignity for people not only in cities, but in rural communities as well:
154. Respect for our dignity as human beings often jars with the chaotic realities that people have to endure in city life. Yet this should not make us overlook the abandonment and neglect also experienced by some rural populations which lack access to essential services and where some workers are reduced to conditions of servitude, without rights or even the hope of a more dignified life.
