Writing skills are so poor today in the US that if you can barely write a proper sentence you are an outstanding writer by comparison. Teachers are instructed to pass every student on effort.the problem goes back so many years.
There has been discussion of “functional illiterates” for quite a long time. I think we have a new category, one which I have not seen discussed at all. I’m referring to people who are literate and who can write but who cannot write clearly or correctly and who cannot think in any sort of focused, cogent way. These people can put words on the page, but the end result is always massive confusion. It’s worse than being functionally illiterate, in my opinion.
