Pope John XXIII
Mater et Magistra §146
Mater et Magistra: On Christianity and Social Progress
146 It is important also to bear in mind that in agriculture, as in other sectors of production, association is a vital need today—especially in the case of family farms. Rural workers should feel a sense of solidarity with one another, and should unite to form co-operatives and professional associations. These are very necessary if farm workers are to benefit from scientific and technical methods of production and protect the prices of their products. They are necessary, too, if they are to attain an equal footing with other professional classes who, in most cases, have joined together in associations. They are necessary, finally, if farm workers are to have their proper voice in political circles and in public administration. The lone voice is not likely to command much of a hearing in times such as ours.
