I can tell you as a high school teacher for 36 years that the only way to insure equality of outcome is to bring the top down! The bottom NEVER gets raised. I once tried "redistributing wealth" using grades as a substitute for wealth, the kids HATED it !!!!!!!!! Even the middle of the "curve" was dissatisfied with the inability to improve as individuals. Those that didn't want to work sat back and got worse, further de-grading the outcome (no pun intended) The over-achievers, tired of carrying all the weight, finally caved and the system collapsed, everyone had failing grades.
