Earlier quoted context omitted.
A business degree makes the candidate over-qualified for managing a mall store is the likely reason. They are afraid of the employee using the position as a stepping stone to a higher paying, higher status job.
I am under the impression that business/communications bachelors degrees were a signal that the degree holder took the easy way out in school. It was considered the fallback degree when I went to college 20 years ago, since anyone could graduate with it with minimal effort.
Communications can be good if your school is in the middle of a communications hub. Which, for US students, boils down to Los Angeles and New York City. But a lot of the worth of that degree comes from its ability to unlock internships and networking inside the two biggest media markets in the US, if not the entire world.
So not entirely worthless but only lucrative in specific cities and markets, and for mostly shibboleth reasons (many friends with communications degrees who also went to school in either city pull in mid-six figures working for big entertainment companies).
But hey, at least you don’t have to actually study anything while spending most of your week at unpaid internships and networking events!
