A related issue, said Pius, is the relation between capital and labour and the determination of fair wages. Pius develops the following ethical mandate: The Church considers it a perversion of industrial society to have developed sharp opposite camps based on income. He welcomes all attempts to alleviate these differences. Three elements determine a fair wage: the worker's family, the economic condition of the enterprise, and the economy as a whole. The family has an innate right to development, but this is only possible within the framework of a functioning economy and a sound enterprise. Thus, Pius concludes that cooperation and not conflict is a necessary condition, given the mutual interdependence of the parties involved.
