I really didn't think things were this bad. I taught freshman English in college for all of one semester once. I have it on good authority that those in both classes went on to be regarded as good writers. This probably had something to do with the fact I was already at the time a professional writer and editor (even if still in the larval stage). But it a had a lot to to with the fact that all of my students had the basics of grammar and usage down. I just taught them techniques.
