Norm;
I agree with you.
But,a lot of people migrate to the hands on trades as a way not to have to learn the skills of writing.
My self included.. But I have enrolled in courses to get my A.A. so I am taking English classes again.
Back to your point, Yes if a tech works on a house of some academic type person and his (her) writing skills are bad, it makes the tech look bad also. Period!
Schools just are not teaching proper English any more. Ebonics are more important to some districts.
Keep up the crusade....
