Means of production refers to physical, non-human inputs used in production—the factories, machines, and tools used to produce wealth — along with both infrastructural capital and natural capital. This includes the classical factors of production minus financial capital and minus human capital. They include two broad categories of objects: instruments of labour (tools, factories, infrastructure, etc.) and subjects of labour (natural resources and raw materials). People operate on the subjects of labour, using the instruments of labour, to create a product; or, stated another way, labour acting on the means of production creates a product. When used in the broad sense, the "means of production" includes the "means of distribution" which includes stores, banks, and railroads.

The term can be simply and picturesquely described in an agrarian society as the soil and the shovel; in an industrial society, the mines and the factories.

Factors of production are defined by Karl Marx in Das Kapital as labour, subjects of labour, and instruments of labour; i.e., the term is equivalent to means of production plus labour. The factors of production are often listed in economic writings derived from the classical school as "land, labour and capital". Marx sometimes used the term "productive forces" equivalently with "factors of production;" in Capital, he uses "factors of production," in his famous Preface to the Critique of Political Economy, he uses "productive forces" (note that this is in the English versions and may depend on the translation.)

Avram Noam Chomsky (/ˈnoʊm ˈtʃɒmski/; born December 7, 1928) is an American linguist, philosopher,cognitive scientist, historian, and activist. He is an Institute Professor and Professor (Emeritus) in the Department of Linguistics & Philosophy at MIT, where he has worked for over 50 years.

Ideologically identifying with anarcho-syndicalism and libertarian socialism, Chomsky is known for his critiques of U.S. foreign policy and contemporary capitalism, and he has been described as a prominent cultural figure. His media criticism has included Manufacturing Consent: The Political Economy of the Mass Media (1988), co-written with Edward S. Herman, an analysis articulating the propaganda model theory for examining the media.

According to the Arts and Humanities Citation Index in 1992, Chomsky was cited as a source more often than any other living scholar from 1980 to 1992, and was the eighth most cited source overall. Chomsky is the author of over 100 books. He is credited as the creator or co-creator of the Chomsky hierarchy, the universal grammar theory, and the Chomsky–Schützenberger theorem.
