Why do professors scale marks and raise the marks of students that don't deserve it?

Would you prefer getting a B while everyone else fails, like in my last examples? It seems not…

Yes, I definitely would. It shows one is an exceptional student to a graduate school if they received a B in a class with a class average of a 30. </p>

If you state they’re incompetent at doing their jobs, what makes you sure that they’ll be competent in grading (since it is, after all, part of their job)?

Don’t misinterpret what I said. My professors are quite exceptional teachers, it isn’t their fault if 75% of the class doesn’t know how to study for their tests and thus fail.</p>
