Am I an elitist? Guilty! Am I a snob? Yes, my lord. Believe me, in the job market, use of argot, slang, chatspeak or any other sign of basic ignorance of the language works against the applicant.
I always required a 500 word hand-written impromptu essay when I hired. I would announce the topic, hand out pencil and paper and give applicants a short period of time.
I was increasingly shocked by the result. I refer you to some of the spelling, syntax and useage on this site, my dear readers, to illustrate my point.
The lower the class, the worse the language.
