What this really is about is not having to grade papers. If you get people to accept the sum (and by extension, difference) of any two numbers can be anything, you can just give every student a perfect grade.
Its about giving the teacher the authority to arbitrarily promote and punish.
If there is no objective standard for grading then the class really becomes about who can stroke the teacher's ego the best. And the teacher has ultimate say in the student's fate.

I wonder who would benefit from that kind of power.
Who makes up an absolutely ridiculous number of teachers again?
