"But if society has to invest 400 man-hours rearing, socialising and training me to do a task, for every hour I can actually spend doing a task, then the value of the labour on the task must be equivalent to 401 unrefined man-hours."
I know what you mean but first I think people underestimate "unskilled" work and, second, with all work, "experience" is worth as much if not more than education.
Also, what is the actual point of comparing skilled to unskilled labor, as in the paragraph above?
