Ever seen someone doing their “unskilled job” all their life? It’s just fucking magic!
The truth is that capitalists hate skilled workers, because those workers have bargaining power. This is why they love the sort of automation which completely removes workers or thought from the equation, even if the ultimate solution is multiple times more expensive or less competent than before.
Nothing is more infuriating to a boss, than a worker that can talk back with experience.
It isn’t superior, but it takes on a different character. Labor is worth itself as an average of the totality of labor.
Training is unproductive labor that is applied over the expected working lifetime. Practical experience is a form of training, yes, but this is earned over an average as well.
Does that make sense? That’s why a seasoned electrician earns more than a journeyman, despite both having training.
Both are true. Some educations create skillful workers, just like anyone practicing a trade over time acquires skills with regards to their tasks. That being said, many degrees are just manufacturing diplomas for middle class and bourgeoisie kids who want to feel superior (and have an excuse to be rewarded as if they were).
Yes, supply and demand also impact the price of a type of labor, but the value created trends towards the average hour of labor.
