Here's a clarifying video arguing the labor theory of value ( #LTV) is correct. It is so, we're told, because it is useful for explaining exploitation (an assertion, btw). Then its subjectivist critics are dismissed as "conservatives" relying on supply and

demand curves (wrong on both counts; see Menger). Then it's argued that the subjective theory of value is unscientific because science predicts (and subjective value doesn't), which not only misses how economics was always done but also inadvertently dismisses Marx (if not any

social theorist prior to Comte). Then it is claimed that the LTV accurately predicts the economy because industries tend to use labor where it is most productive--a point that is in fact explained (if not proven) by the equilibrium analysis previously dismissed. And finally, the

presentation of some simplistic aggregate data analysis indicating how the evolution of price of labor tends to follow its productivity. This supposedly proves LTV, but disproves supply and demand curves. Speaks to the power of confirmation bias, but nothing more.
