Salary isn't based on which degrees you have, it's based on what job you're doing. It's inane to compare a computer programmer's salary to a teacher's salary.
That aside, 68k is perfectly reasonable for a job with fantastic security, summers off, lots of vacation time where you get to work with children. Also, when I started working as a programmer, my salary was ~72k which is not much more and I had no trouble living off it. Of course the ceiling is higher for me but that's the market's doing.
This comes at the expense of having absolutely no flexibility during the school year and usually plenty of long days & weekends, and summer has things like professional development / continuing education keeping it from being a long work-free block.
It’s not bad but it’s not a compensation game changer. One other thing to remember: for a teacher, being out sick is almost as much work as a normal day. The tempo of a school year means that a lot of people need a couple weeks to unwind at the end of the year.
