There is a dirty little secret out in the world, certain big companies are hiring MS or better only. The reason being with grade inflation, a BA is BS. Students have to pass a test to get into grad school, plus they are picky to boot.
You might be right about companies hiring MS or better, but not for this reason. My experience is that grade inflation is more of a problem in graduate school than on the undergraduate level. Many graduate students who attend on a part-time basis are having some or all of their costs covered by their current employers, and these employers usually require a grade of B or better in order to have their costs reimbursed. Instructors know this, and grade their students accordingly.
