The types of students who are entering college needing dramatic remedial math are not the ones you want to fail in large numbers.

Sounds somewhat defeatist. Besides, the teacher nevers wants to fail anyone. Teachers would be happy if all students performed well.

If I may assume, I think GP is alluding to the likelihood that such students are going to be minorities from poor socioeconomic backgrounds. If they are failing in large numbers, that will open the door to claims of systemic discrimination.
