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.
Then I suggest using the word more valuable skill than being more skilled. More valuable skill since it implies rarity and not some sort of hierarchy. That’s my take anyways from the word “some jobs require more skill”.
