Just 38% of recent college graduates (from 2006 on) "strongly agree" that their education was worth its price, a new Gallup-Purdue Index study finds, and 8% felt strongly that it wasn't worth it. The number rises to 50% for all college graduates (more than 30,000 total) who were surveyed. As Vocativ notes, the average amount of student debt for a 2015 graduate is $35,000. Want to make sure your kid feels his education is worth its hefty price tag? Encourage him to develop relationships with the faculty: Alumni who felt their professors cared about them, whose professors got them excited about learning, or who had mentors were much more likely to believe their education was worth the cost.
