Way late to the punch here, Flesh…
I have never heard of Wayne Fazio but he definitely did not invent the producerist perspective. It has been around for a long time, at least the nineteenth century if not the eighteenth or even the seventeenth.
For example, William Manning in “The Key of Liberty” (1799) articulates the notion of “the few and the many” in which the many are productive laborers and the few are speculators, money lenders, those who earn money from rent, etc. Indeed it was quite common in the eighteenth century to view labor as the creator of wealth (Smith is the exemplar) and we can see this perspective articulated in the seventeenth century by John Locke in his Second Treatise.
French artisans in the nineteenth century articulated a similar perspective through their concept of ouverismé. This was picked up by Proudhon and promoted by other anarchists throughout Europe and the Americas.
Have a nice weekend.
