That’s just how everything works though?
Not every electrician is going to be working on panels, some just wire plugs instead, people specialize and are payed differently depending on the tasks. Very rarely do you find someone who does the entire trade regulary. They’re not going to be as good or fast as the ones that specialize, so it’s a delicate balance.
Just like every graphic artist may not be being Mona Lisa’s, they could be doing mangas or just heads or something.
Not all doctors are cancer specialists, some are just family doctors, that’s literally how every job and training works everywhere.
Do you think that everything you learn with a degree is used while working? Because they’re taught useless shit too.
