That Will Learn 'Em!

I liked comment #6 here:

I am high school teacher- I have done experiments with students’ grades- they have to pay a tax over 80% - with tax getting steeper after 90 and 95%. I often hear- its not fair- I worked for my grade.
To complete the wealth-spreading analogy, part of that grade tax should be added to the lower-scoring kids' grades.

This would probably be the most important lesson the students learn all year.
