Mater et Magistra §134
Mater et Magistra: On Christianity and Social Progress
134 For this reason, too, investors are more inclined to put their money in industry rather than agriculture. Farmers are unable to pay high rates of interest. Indeed, they cannot as a rule make the trading profit necessary to furnish capital for the conduct and development of their own business. It is therefore necessary, for reasons of the common good, for public authorities to evolve a special credit policy and to form credit banks which will guarantee such capital to farmers at a moderate rate of interest.
