Most of the jobs don't require you to be able to write well at all - especially not university level writing. Really, all most folks need is the ability to communicate effectively in person or over email. You might - just might - be required to write a letter. Of course, these skills are ones that a store manager at any random retail or dining establishment needs too, and some of these 'middle class' jobs require nothing much at all (if it is a factory that pays well enough).

Besides, plagiarism isn't really about writing. You can lump it into two categories: Cheating, which isn't most folks' intention, and more importantly, giving someone credit for an idea. This last one is something folks need to do in some professions. Don't take an employee's idea and call it your own, same for something your boss has you pass along. Don't pretend something is your own idea when it was implemented at a job you had years ago. This version of plagiarism is vastly more important than writing skills (which can be taught without needing to address plagiarism).
