I got a degree from a prestigious journalism school (long ago!). A couple of other students struggling with writing composition sought me for a study partner and were *amazed* that I consulted a dictionary, thesaurus, and almanac routinely when writing. They just wanted to be on television.
Historically, illiteracy is the norm. There are entire cultures even today who are, for all purposes, verbal communications only. It was mostly government that forced literacy on schoolchildren. An increasing segment of the population is reverting to a range between illiteracy and anti-literacy.
I see more and more podcasters and television talking heads whose speech gives away that they don't read and definitely don't write - and these are supposed professionals in the Communications Industry.
As the internet communications bandwidth increased, it has gotten harder to find a one-page info sheet on something, but instead I find 50 videos of varying length, quality, and questionable research by anti-literate wannabees.
The workplace is backsliding as well. With the prevalence of video meetings through mobile phones, the quality and quantity of clear, literate communications is declining.
