If I could change financial legislature that affects students directly it would be to increase state funding of public schools and colleges. College has also become very expensive due to low government funding and there are no quality learning materials.
Students with at least a 3.0 average could apply for a loan for college. It would have to be paid back in cash or in community service within 5 yrs of the loan being granted. Of course, you would have to be near or at poverty level to qualify.
