Just to play devil's advocate, my friend who went to Harvard became a teacher after working at a top consulting job for a few years after graduation. He became super jaded with his job and ended up getting a masters in teaching since he likes working with kids. Now he teaches at an underprivileged high school and makes way less money but he really loves it, so a teaching degree isn't always necessarily a backup plan.

People just what to do things they love. Your friend loves teaching. Some loves money and prestige
