There is a total stop on innovating in non-human math homework grading.
As a result, there is an artificial scarcity in math homework grading resources.
However, /sci/ readers are students, and student math homework grading costs are paid by parents, not students.
So, oddly enough, /sci/ readers discount the value of a scarce resource: attention of math homework graders.
The readers here simply don't ask the hard questions: how are they exploiting the math homework grading resources that are made available to them?
What is the last time you heard anyone in the West explain their approach to exploiting the math homework grading resources that have been made available to them?
You've never heard anything like this.
