> a person who's attending school in order to improve their lot in life (because credentials count for so much)

If every person at the school had this reasoning, the credentials wouldn't count for anything.

The credentials only count for something if enough of the people graduating are actually fulfilling this promise of self improvement in the subject of their studies.

The cheaters are literally freeloading off the prestige of the credentials produced by the people who do put in the effort. If that group of people did not exist, the credentials would be useless to the cheaters as well.
