Obviously, it would be great if all employers looked at all factors. All but the biggest employers probably are going to, anyway.

As to this notion of inequality, it seems you (and Dave, for that matter) are ignoring the inequality of professors between day sections. Surely, we must also ensure that all day section classes are taught by the same professors. Some might give more reading. Some might do more with class participation. Some might grade down in the curve while some grade up. That I took a course (in the day, by the way) with a professor who grades more harshly in the curve than he had to surely means that my grades from that semester can't be used to compare against others.

The curve allows for all of this. If professors who teach in both sections believe, as Dave has told me at least one does, that the quality of the evening students' work is lower, there's no requirement to meet the maximum boundaries of the higher grades in the curve.

In the end, we all take different classes, classes with different professors, different numbers of classes, and classes with varying grading methods. That's hardly a system that's well designed to compare students. But that's the system we have.
