It's a bad example because it's incomplete and false. Even your elaboration is incomplete and false.

Job postings require degrees for a multitude of reasons other than introducing a common standard of communication (like proof of experience and background, certification and legal purposes)

I am a pretty dilligent reader. Does not help at all when everybody else is not a dilligent writer (and even those who are, they are not all the time).

You can either keep enforcing your point in your work (and social) environment and get frustrated, or accept that any form of communication requires repeating, examples and explaining in a different way, no matter how precise, concise and to the point you are. I've tried the former, and while it allows you to consider yourself smarter than everybody else, even that wanes after a while.
