polarscribe, it's not so much about agreeing with Murray's arguments as it is seeing why he's suggesting that the B.A. not be an auto-requirement for all jobs. There was an article a few years back by an anonymous community college professor who wrote about teaching english literature to part-time students who needed an english class...for their day jobs as police officers. If they wanted to be promoted, they needed a two-year degree. It had nothing to do with the job's duties. A lot of the students couldn't pass the first time, so they had to take the class twice or more, paying each time. This wasn't an area with public cheap community colleges, so it meant taking out loans, or spending money people didn't have. Not to mention not having time for other things, arranging for childcare, and so on.
Now, if you're a publisher and you want to hire some new copy editors then yeah, asking for a B.A. makes sense. Or you could ask to see their SAT CR scores. That's the kind of job where there is "a tight link between the test and actual job requirements", as it says in the quote glido provided.
