Robin Hanson claimed that opposition to GPA redistribution paired with support of income redistribution is evidence of "natural hypocrisy." Andrew Sprung counters:
GPA is more tightly tied to individual performance than earnings are. Granting that a) grading is an imperfect measure of the quality of student input, and b) earnings bear some relationship to performance, it's still true that student performance bears a closer relationship to grade than the social utility of the average person's work does to that person's earnings.
Also, we have the right as a community to take some pay back as price of admission, and no right because no motive to take GPA back. Collectively, we pay someone for performing a service because we want what they're selling. Taxing back a measure of that payment is as organic to human society as paying it out in the first place, since tax of one kind or another is the price of admission to any human community. "Taxing" the measure of school performance, on the other hand, only makes sense if you regard GPA as a commodity rather than as a condition for further learning.
