>But this kind of misses the bigger picture of what Marx was getting at rather by getting lost in the weeds about price definitions and really is a critique of Ricardo more than Marx. This is very true, and cannot be overstated. Often, the criticisms of one theory are actually much better direceted at a predecessor theory. Students in a history of economics course, or a regular economics course, may learn of the "labour theory of value", but they may learn either Smith's, Ricardo's, or Marx's, and assume that the theories are the same, or that the same criticisms apply to all of them. There are good and serious criticisms of the "labour theory of value" from those unsympathetic (and even those sympathetic) to its apparent normative conclusions. It's a shame that many people seem to confuse one thinker for another, especially when each boasted of their improvements (Marx, for example, writes "I was the first to point out and examine this [...]" when writing on the "LTV" and discussed the law of the tendency for the rate of profit to fall again in his original understanding, despite being extremely well read on - and critical of - his predecessors).
