Why should a BA/BS be valued?

Here is a provocative piece by Charles Murray arguing that employers should not esteem BA degrees over degrees from community colleges. A representative quote:

The benefits of discarding the bachelor’s degree as a job qualification would be huge for both employers and job applicants. Certifications would tell employers far more about their applicants’ qualifications than a B.A. does, and hundreds of thousands of young people would be able to get what they want from post-secondary education without having to twist themselves into knots to comply with the rituals of getting a bachelor’s degree.

It’s a little odd, I think, that Murray seems to value education primarily with respect to employment. I thought the aim is different: not necessarily to make capable workers, but to make more-educated people. Silly me.
