“Unlike President Biden’s student loan schemes, this plan addresses the root causes of the student debt crisis. It puts downward pressure on tuition and empowers students to make the educational decisions that put them on track to academically and financially succeed,” he added.

Lowering people’s ability to borrow doesn’t really address the other problems which underlie high tuition costs - such as newer facilities costs, more administrative staff (both of which, IMO, heavily relate to the competition between schools to provide the most services to their students and court new student admissions), and decreases in federal and state funding coming from tax revenue which has led to much of the financial burden being passed onto individual students.

Plus, as @misguidedfunk mentioned, we already tell students their upfront cost of attendance - multiple times even before they decide to enroll or start classes - and they have to acknowledge it as part of receiving aid.
