If a student is not doing well in school, it makes no sense to just "give" that student a higher grade, for "equality" with the rest of the class. You need to help that student get better, so he/she can achieve the higher grade on his/her own. If a student can't do multiplication in a test, you don't just "give more points" to that student, for "equality" in the classroom. You need to teach that student to learn multiplication. You need to bring that student "up" and not everyone else "down".
