Brilliant suggestion after the 13 minute mark about "MARKSism", where halfway through a course, a teacher can

(1) pool all the MARKS (grades) and hand them out at random, and lazy students can suddenly get high grades without having done any work at all, and
(2) ask students to explain why the overall average grade has suddenly dropped. Those who can explain it properly will pass the course, the others will fail.

Marxist indoctrination defeated in one semester (if the predictable SJW uproar doesn't promptly get the teacher suspended or fired ).

An economics class would be ideal, but other teachers can get in on the act, too, as long as students care intensely about their grades.
