No, the goal is cheap labor, they hire more PhD students than there are tenure track positions, this was a common gripe when so many undergrads commited suicide at IU, they threatened to shut down the newspaper if they reported it and told grad students who were basically extorted into finishing under the threat their advisers would forever gatekeep roles that would take them out of precarity. (That's why I dropped out, worked briefly in policy, learned to hack, then sold stock out of my retirement fund to get an open source intelligence certification from Bellingcat -- because THAT MANY sets of people refused to follow basic social norms.)
