Every time I reach a crossroads in my career, I find myself considering going into teaching. Then I recall the cost of becoming credentialed (somewhere in the $20k-$90k range) and the fact that I would make less than half of what I make now, and I can't bring myself to take the option seriously. It makes me angry that, if you finish your PhD (and maybe even if you don't), you would be perfectly qualified to teach college students, but teaching seniors in high school is out of the question without you going through still more schooling and hoop-jumping. Myself, I have bachelor's and master's degrees in mathematics and applied mathematics, but it doesn't matter. The public schools don't want me. Maybe I wouldn't be a good teacher, but maybe I would be. We'll probably never find out.
