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.
I don’t think it’s anyone. The difference is that one job training requires extensive facility and infrastructure in place to do the training, while the other is trivial. You can train a lot of people to flip burgers with a lot less resources than training a surgeon to do surgery.
