This quote spread rapidly in the United States after appearing in a column by Molly Ivins (24 November 2002). It is repeated often and sometimes attributed to the "Fascism" entry in the 1932 Enciclopedia Italiana. However hard copies of the 1932 Enciclopedia Italiana exist in numerous libraries and the alleged quote is not in the text, nor is there anything that would support the alleged quote. A vaguely similar statement does appear in Doctrine of Fascism.
We are, in other words, a state which controls all forces acting in nature. We control political forces, we control moral forces, we control economic forces, therefore we are a full-blown Corporative state.
The same document explains that the "corporations" (corporazioni) on which the Fascist state rested were its own creations, modeled on guild associations and not private companies, which Italian normally calls società. For details see "Mussolini on the Corporate State" http://www.publiceye.org/fascist/corporatism.html by Chip Berlet.
