They "should" be near the federal reserve interest rate which is currently 0% (2010-2016) but predatory lending takes advantage of people who grow up being told that they need college to have a chance of success in life. Dangle the carrot and hit them with student loan interest rate stick when they reach for the carrot.

It seems truly unfair how far they are from the federal reserve interest rate.
