Pacem in Terris §102
Pacem in Terris: On Establishing Universal Peace in Truth, Justice, Charity, and Liberty
102 We advocate in such cases the policy of bringing the work to the workers, wherever possible, rather than bringing workers to the scene of the work. In this way many people will be afforded an opportunity of increasing their resources without being exposed to the painful necessity of uprooting themselves from their own homes, settling in a strange environment, and forming new social contacts.
