Taking a longer time to graduate to become the “world expert” in their field is fine if grad students weren’t paid next to nothing for the 60+ hours a week that they are expected to work. As it is now it’s better to finish as quickly as possible so they can have a real life.
Isn’t this sort of how all terminal degrees work? MDs, JDs, etc are all putting the candidates through the wringer, for relatively low wages, until they’re “experienced”.
