It's limiting who can even enter college. Blyth specifically recommends "Free College Tuition". I (perhaps unwisely) mentioned the milder goal only addressing current student debt with the goal of avoiding being dismissed as "marxism".
I strongly recommend listening to Blyth's actual explanation (in this or his other talks & publications), not my poor-quality summary.
