Mater et Magistra: On Christianity and Social Progress
77 Experience suggests many ways in which the demands of justice can be satisfied. Not to mention other ways, it is especially desirable today that workers gradually come to share in the ownership of their company, by ways and in the manner that seem most suitable. For today, even more than in the time of Our Predecessor, "every effort must be made that at least in future a just share only of the fruits of production be permitted to accumulate in the hands of the wealthy, and that an ample sufficiency be supplied to the workers." (29)
