(And they can’t explain why Keynesianism collapsed either)
This is part two of the series, “How fiat currency killed Marxism”. Part one is here.
At the high level of abstraction of Capital, money has to be a commodity, because Capital presents a theory of a “pure” capitalist economy, without state intervention. And in the 19th century laissez-faire capitalism (without state intervention) that Marx was analyzing, money was a commodity and money had to be a commodity in its functions of measure of value and store of value. However, in the post-1973 contemporary capitalism, money is no longer a commodity (i.e. is no longer convertible into gold at a fixed exchange rate), and money does not have to be a commodity in Marx’s theory. The state-guaranteed fiat money serves the same purpose as gold under the gold standard – it provides an observable, homogeneous, quantitative, and socially valid expression of abstract labor. —Fred Moseley, Money has no price
If Keynesian currency devaluation allows the state to maintain production for profit by reducing the real value of wages, why were Keynesian policies abandoned in the late 1970s for neoliberalism? To explain why this happened, requires some discussion of the problem with simple Keynesian “full employment” policies.
