There is a Wikipedia page for the Criticisms of the Labor Theory of Value.
But there is no Wikipedia page for "Criticisms of the Criticisms of the Labor Theory of Value". Even Google doesn't turn anything up.
I have not read enough theory to even fully understand LTV, let alone understand its criticisms. But I'm assuming there are some Marxists who have written the "Criticisms of the Criticisms of the Labor Theory of Value". What would these be? Right now you get the impression that the "Criticisms of the Labor Theory of Value" are going unchallenged.
Because they didn't read Marx for basic comprehension. That is always the answer. Instead, the critics seem to just copy and cite each others' misapprehensions.
The most common criticism is to declare a dichotomy between LTV and marginalism, which to me implies that they don't really understand either of them because they're confusing pricing with the Marxist concept of the aggregate value of commodities. Anyone who read Capital while conscious will know how ridiculous this is, given that Marx explicitly differentiated this from exchange value.
Weird how everyone from left to right seem to share this one weird habit
