The Perkins Loan is the best student loan available.
So that would be at most $500, while the average Perkins loan is $2,000. When you do the math, the net loss to students (in federal aid each year) would be at least $1,500.
Congress is going to hear from student loan professionals at the school because they're the closest to the fight. Certainly members of Congress will listen to them, but the folks they will listen to the most are students who are Perkins Loans borrowers.
