The author of this piece mentions classical political economy, but not Marx, its most trenchant critic. Marx's most interesting and compelling contribution - until recently seldom understood in the English-language literature - was his theory of the "value form" and money as the "necessary form of appearance of value". This contribution is further masked by the common practice of identifying "the labor theory of value" (there is no such singular theory) as Marx's principal contribution. In fact, he was a critic of the many (contradictory and inconsistent) "labor theor[ies] of value" in circulation at the time. "According to Marx, value and money are inseparable yet not identical: without money there can be no value, yet money is not value. Marx’s thesis of the inseparability of value and money overturns the classical theories of value and money and establishes new concepts governing the theory of price. These new concepts rule out the ordinary assumption of price theory, namely, that value is the independent variable that explains the behavior of price, which is conceived to be the dependent variable." - Patrick Murray (https://www.mtholyoke.edu/courses/fmoseley/conference/murray1.pdf https://www.mtholyoke.edu/courses/fmoseley/conference/murray...)
