The Dodo bird said "Everybody has won and all must have prizes."
In elite colleges today, "A" has become the average grade. Therefore, high grades have little impact on employers.
From Why Grade Inflation Hurts Social Mobility:
Grade inflation, in my view, is a quite deliberate project of our most elite schools to secure the elitist advantage of their students from effective competition. Indeed, the center of grade inflation is the Ivy League. As far as I can tell, the grade inflation is meant to protect the "brand" of the meritocrats earned by being admitted. To be sure, it's not that the students at Harvard or Princeton don't work hard. It's just that their efforts occur in a safe and secure environment. They're protected from real competition from excellent students at lesser schools. Nobody is ever to say that an A at my Berry College is as good as an A or even A minus at Harvard. So we professors in the sticks can't really win by sustaining grading standards too different from those used by our most prestigious schools.
