Or rather a problem, I should say, but a fairly big one. I brought it up the other day to someone who has studied economics and worked in that field. She had never heard of it, so later I went looking around on the web for some sort of quick intro. And almost everything I found gave the impression that it is some sort of specifically Catholic idea. Search for "what is distributism?" and Google immediately gives you this definition, from the Wikipedia article:
Distributism is an economic philosophy that developed in Europe in the late 19th and early 20th century based upon the principles of Catholic social teaching, especially the teachings of Pope Leo XIII in his encyclical Rerum Novarum and Pope Pius XI in Quadragesimo Anno....
And the first of the search results is this FAQ from The Distributist Review, which begins:
Distributism finds its roots in the social and economic theories articulated in the documents of the Catholic pontiffs, beginning with Pope Leo XIII’s “Rerum Novarum.”
The page is a good summary, and I don't mean this as a criticism; after all, what it says is true. But it, and everything else on the first page of search results (including a couple of pieces arguing against it), leaves the impression that distributism is some Catholic thing, based mainly on the authority of the Church and of interest mainly to Catholics, and rather traditionalist Catholics at that. If I were a non-Catholic, possibly not well disposed toward the Church, I'd certainly think that, and probably pay no more attention.
But although the ideas have been propounded mainly by Catholics, there's no intrinsic reason for that. And it's certainly not a doctrine of the faith. It's a tribute to the general good sense of Catholicism that distributism emerged from it, but there's nothing in it that isn't accessible and acceptable to ordinary reason and common sense.
I know this is all pretty obvious, but it just struck me forcibly when I brought up the subject with a non-Catholic. I don't know how it can be done, but I doubt distributism will ever gain much influence until or unless it can break out of this Catholic ghetto.
