You're right about the pay for teachers. However if you look at the way it's worked out for adjunct professors at the college level, the part-time pay is even less, plus they miss out on benefits. If there's any high school teachers' union involved, I'd bet they'd be against allowing part-time teachers.

Once I chanced upon an ad for high school comp sci teacher. They were willing to waive the Master's degree requirement as well as the teaching credential requirement. As you note, the pay was ridiculously low, about 30-35% less than industry salary for a fresh-out-of-school graduate. Would have been nice though, for someone eager to teach but wanting to skip the 2-4 years of extra training.
