Granted, teaching 10 well-off adults is easier than 30 poor kids.

This doesn’t explain why all math classes everywhere from about 6th grade and up are designed as if we’re raising an entire generation of mathematicians. What good does memorizing proofs do? Why do we focus so much on the quadratic equation? Algebra is a useful skill that schools systematically beat a hatred for into the masses…in order to pretend they’re doing something academic and scholarly?
