Imaginary value of own labour and effort versus exchange value in the eyes of other market players. Your afore mentioned "labour theory of value" apprises the first but ignores the second (both as a component of some global-whole value essence, or as a standalone thing). :)

Are you sugesting (by refering to that theory) that "fair value for a labourer to get is" only the first? What about other questions I've rised?

Could you just comment instead of refering "read the book" and leave guesing of what do you exactly think or imply as answers? I have my opinions, I have my questions – now I'm fishing for others – looking for discusion, opinions, questions (why would I comment otherwise). You are able to keep a discussion, if you know the topic, arn't you? I mean without using an avoidance tool in style of "go read a bible or you have to have a belief and then you'll understand". Just talk, explain in your own words as you inderstand it, if you understand it, and if you have an opinion on questions asked at all.
