teacher[s] … During the summer, they can try to get a second job, but they probably can’t do better than $10/hour
You can earn $40/hour as a personal tutor without any qualifications beyond an ivy-league degree—I’m sure qualified teachers could command as high an hourly rate.
That’s reasonable—I think some teachers probably can do this as a part-time thing on top of teaching. Keep in mind though, that tutoring work is highly variable by time of year, not very available in some places (I knew zero students with private tutors of any kind in my hometown in Kansas), and can have high transportation overheads. Another way to look at is that if an option that good were available to all teachers, you’d never see teachers getting food service jobs.
In either case, my main point is that the way someone earns marginal income can be completely different than the way they earn their average dollar.
