| "The value of a product is equivalent to the amount of labour exerceted in its production" This is one of the most problematic statements ever made in Econ. The 'value' of a product is different for everyone, and it's what you (or anyone else) will pay for it. The idea that 'work = value' is one of the most distortionary ideas in business, even today. Just had a discussion today about pricing a product, and it was derived from component prices. Trying to convince a room of people that 'price is not a function of cost' ... in 2017. Yes - when things are commodities, often, price is a function of cost, because competitive pricing means just a small margin above cost, which will roughly be the same for most. |
Labor is what's gone in, use is the inherent/intrinsic value in the object, and exchange value is what people will trade in exchange for it. That's a bad summary, and there's a lot more to the dialectic examination of them.
Reading Capital (along with David Harvey's lectures) is worth it if you find these things interesting, it's a deep analysis of markets and capital.
