I don't really see why some no name university can confer a bachelor's in some bullshit field, but the respectable local trade school cannot confer a bachelor's in plumbing. They honestly have more of a right to do so.
That's an accurate name, and only seems pejorative if you see learning a trade as lesser than studying academics.

This misunderstands what the different kinds of credentials are.
Why should there be a difference in the degree being conferred at all? And if so, why not split off the departments that confer degrees with a low-earning potential and call them "entertainment schools" or something?
You are asking why there "should" be a difference between a CCNA cert and a Computer Science degree. That difference isn't a "should" thing, it's an "is" thing. They are fundamentally different.
> why not split off the departments that confer degrees with a low-earning potential
Earning potential is unrelated to the distinction between trade certification vs academic degrees.
Terms have meanings and they matter, even if you don't choose to bother to understand them.
