and decision than his master of steel and iron". Noam Chomsky contends that there is little moral difference between chattel slavery and renting one's self to an owner or "wage slavery". He feels that it is an attack on personal integrity that undermines individual freedom. He holds that workers should own and control their workplace. Many libertarian socialists argue that large-scale voluntary associations should manage industrial manufacture while workers retain rights to the individual products of their labor. As such, they see a distinction between the concepts of "private property" and "personal possession". Whereas "private property" grants an individual exclusive control over a thing whether it is in use or not and regardless of its productive capacity, "possession" grants no rights to things that are not in use. In addition to anarchist Benjamin Tucker's "big four" monopolies (land, money, tariffs and patents) that have emerged under capitalism, neo-mutualist economist Kevin Carson argues that the state has also transferred wealth to the wealthy by subsidizing organizational centralization in the form of transportation and communication subsidies. He believes that Tucker overlooked this issue due to Tucker's focus on individual market transactions whereas Carson also focuses on organizational issues. The theoretical sections of Studies in Mutualist Political Economy are presented as an attempt to integrate marginalist critiques into the labor theory of value. Carson holds that "arising as a new class society directly from the old class society of the Middle Ages, [capitalism] was founded on an act of robbery as massive as the earlier feudal conquest of the land. It has been sustained to the present by continual state intervention to protect its system of privilege without which its survival is unimaginable". Carson coined the pejorative term "vulgar libertarianism", a phrase that describes the use of a free market rhetoric in defense of corporate capitalism and economic inequality (see economic liberalism and right-libertarianism). According to Carson, the term is derived from the phrase "vulgar political economy", which Karl Marx described as an economic order that "deliberately becomes increasingly apologetic and makes strenuous attempts to talk out of existence the ideas which contain the contradictions [existing in economic life]". Economics as anarchist strategy Economic secession has been variously defined by sources. In its narrowest sense, it is abstention from the state's economic system—for instance by replacing the use of government money with barter, local exchange trading systems, or commodity money (such as gold).
