Loans are most beneficial only to lenders, Wall Street tycoons, and the top 1% of the population.
Universities and colleges have an abundance of useless (from job / career / wages point of view) courses and programs. Students are lured into them with easy student loans.
Student loans are a complex world. The only people who benefit in any complex scenario are the top 1%.
Banning all student loans will force universities to provide means of earning for all students. Because they cannot survive with only rich students.
Many countries do not have student loans, still their students are exceeding US students in many areas; while graduating as free birds.
Let all our children graduate with zero loans.
