The issue with Benkei was about Marx's value theory of labour. That actually has to do with supply and demand. — ssu
Sorry, but markets and the market mechanism of demand and supply work far better to explain economic issues. Not a dubious theory based on "labor" making the value of something. — ssu
Are you not aware of Marx's writings on supply and demand? It's covered quite extensively in the
Grundrisse and
Capital (which I would hope you would have read before jumping into criticisms of Marx). Marx wrote about the limitations of treating supply and demand as an economic law as it was the predominant bourgeois economic theory in his own time (e.g. Say, Bastiat) and which was further criticized by non-Marxists as well, decades after Marx (e.g. Keynes).
I'm baffled by the Menger quote you cite as it includes sloppy misreadings of Marx. Value for Marx in his Labor Theory of Value is determined by
socially necessary labor time in a given society, which isn't synonymous with "large quantities" of labor as Menger writes. No where in the quote provided does Menger grapple with Marx's definition on his own terms. It's unclear if Menger does so elsewhere. I wouldn't be surprised if you just googled "Criticism of Labor Theory of Value", and
copied and pasted the Wikipedia entry.
Menger also confuses Marx's definition of
value as conflating with a definition of
price, whereas Marx is very careful to separate the two and that there are of course deviations between the two. But let's think about the brief example within Menger's quote using Marx's actual analysis and see why the former's criticisms is so absurd. Menger asks why the consumer should care about the productive origins of a commodity in regards to price (which Marx would call commodity fetishism). Fair enough, but what about the capitalist? In order to have a product in market she has to have a labor force comprised of wage laborers who require monetary compensation (and also require reproduction, i.e. they need to minimally feed, clothe, and shelter themselves and begin the working day again). She will additionally need the raw material along with the machine(s) or other technology that the laborers will use in producing her commodities. Likewise, the raw material requires wage laborers to extract and distribute to producers, as do the machines which need laborers to be build. The capitalist who requires and gathers all this, for producing her commodity, needs to take these costs into account when positing or determining the market price of her commodity. The capitalist ideally wants to keep the price high, in order to maximize their profit rate, but Menger's generalized consumer can simply choose not to buy if the price exceeds their use value, and the capitalist can adjust the price lower, accordingly. However, if the price is too low then the capitalist at best makes no profit (in which case, why enter production at all), and at worst she loses money due to these productive costs. As Marx writes in the Grundrisse (chapter 2):
The price of a commodity constantly stands above or below the value of the commodity, and the value of the commodity itself exists only in this up-and-down movement of commodity prices. Supply and demand constantly determine the prices of commodities; never balance, or only coincidentally; but the cost of production, for its part, determines the oscillations of supply and demand.
And if Menger's consumer still doesn't accept the asking price, if no consumer accepts the price, then we have an economic crisis, a crisis of overproduction/under consumption.
Summarily, this is the subterfuge behind bourgeois economists; hiding the details of production, including the labor force and it's struggles, behind a veil in order to direct attention to supply and demand in the marketplace and away from labor concerns.
All the leftists would be eating each other over the correct interpretation of Marx. — BitconnectCarlos
That sounds far better than debating if, say, Black Lives Matter is a terrorist organization or if political correctness is Orwell's worst nightmare or some other crap.
