>>11281534>>Because the labor theory of value in which everything is based is wrong.>Prove it.Let's summarize the LTV as "The value of a commodity equals the sum of both the value of the means of labor and the value newly added by the worker in proportion to the duration and intensity of their work" and check that it is not true using reductio ad absurdum.
If we take a completely new pen and use it until it's empty, its value is increased according to the LVT. However, the price of a new pen is (in general) higher than the price of an empty pen. Thus, the premise (the LVT) should be wrong.
