I did once think that if the meeting were to be transcribed, people are outputting paragraphs of text in a short amount of time, just verbally. But keeping up with that is pretty draining, as you have to listen and process it, whereas with reading you can skim and re-read things easily.
I sometimes think people's basic skills - reading and typing - are underdeveloped or not assessed, and they should be assessed when applying for a job that involves reading and typing. But I don't even think people consider reading/writing skills when looking for staff since the assumption is that everyone's is good enough.
