I covered this before when Caritas In Veritate came out, I thought maybe I should do so again. Popes speaking on economic issues have been vexing economists since 1891. Paragraphs 50-64 of Evangelii Gaudium is nothing new.
And now, the eight Papal documents, so far, on economics, so that you can get a feeling of the history of the Doctrine of Distributism:
Rerum Novarum from Pope Leo XIII
Quadragesimo Anno from Pope Pius XI
Mater et Magistra from Pope John XXIII
Populum Progresso from Pope Paul VI
Laborem Exercens from Pope John Paul II
Centesimus Annus from Pope John Paul II
Sollicitudo Rei Socialis from Pope John Paul II
Caritas In Veritate by Pope Benedict XVI
Evangelii Gaudium by Pope Francis
People think that Catholic doctrine never changes- but it's dogma that doesn't change, doctrine changes ever so slowly because of the concern for human error. The Doctrine of Distributism is as solid as any other form of economics I can think of, but unlike communism, which requires total subservience to the state, and capitalism, which requires total subservience to self, distributism is duty to protect other people's rights and justice to fulfill other people's needs. And in return- other people have a duty to protect YOUR rights and fulfill YOUR needs. Interdependence, rather than independence.
And that ethic I think is really worth thinking about.
