Perhaps it's not grade inflation that's the issue. Perhaps it's time to set aside the outdated ideology that grades must always adhere to a bell curve where some percentage of the class must be failed and some percentage must be passed even if the class is comprised of 35 perfect clones of Albert Einstein.
Even further, what an asinine system to begin with. What good does a grading system based on the success of one's immediate peers do anyone? What information does that offer anyone? Maybe I got a 4.0 from Harvard but, if we using a bell curve system of grading, that may tell you that I was in a particularly weak class or that I actually was the strongest student in Harvard history. You'll never know.
