You seem to be under the impression that it is somehow unfair that people don’t have to do everything themselves, and can leverage their social networks to achieve more than they could on their own.
I suppose it is unfair to those who, by disability or temperament, don’t build social networks. But so what? Those people are no worse off than they would be in a world where everyone is a shut-in.
And don’t bring socioeconomics into it; social access to a specific typesetting machine might be less likely at lower income, but access to e.g. machine shops is more likely, and arguably more valuable.
Yes, it is empowering that people can achieve more by working as a team with their friends and family than they could on their own. Like any good thing, there are downsides, and we should be wary of nepotism in zero sum things like hiring, but gp’s typesetter was going to sit idle had they not used it. This is an empowering story.
