>>2416410Cockshott has several video essays on how asinine supply and demand are and how the classicals AND Marx both essentially agreed that price formation mainly came from cost of production, particularly the cost of labor, and that supply and demand curves were introduced by Marshall to deliberately obfuscate this fact by pretending that prices are merely the interplay of market factors. But one question you can ask is why does commodity A have an equilibrium price X and commodity B have an equilibrium price Y? Once supply and demand are in equilibrium they cease to explain anything. the equilibrium price formation of the commodity must be explained not by after-production factors in the market but by the factors of the production of the commodity itself.
If commodity X is made out of raw materials Y and Z, then the socially necessary labor time required to acquire, refine, and assemble those raw materials into commodity X must explain its equilibrium price, and supply and demand can only explain temporary deviations or fluctuations around that labor price.
But people want to get hung up on semantics and ignore the fact that the economy simply could not functino without labor and laboring masses hold massive leverage over the economy if they would only organize and pursue their political interests collectively rather than individually.
People also want to divide the laboring masses on the issue of age, sex, gender, race, ethnicity, language, nationality, "world" (1st 2nd 3rd), and silly things like whether you can save money or not by depriving yourself of certain needs or wants.
