From the wikipedia, with emphasis:
Distributism favors the elimination of social security on the basis that it further alienates man by making him more dependent on the Servile State. Distributists such as Dorothy Day did not favor social security when it was introduced by the United States government. This rejection of this new program was due to the direct influence of the ideas of Hilaire Belloc over American distributists.
Well, I've got to get a book about this now. This is in sync with a lot of ideas I've developed independently (or so I've thought) anyway.
