Have you checked how much high school teachers actually make? It's not much.
Still better than sweeping floors definitely. And you can work as tutors if you are good with kids.
you know I would go back to cleaning toilets if it paid the same as staring at a screen
Actually that's not generally true. Janitors at least work 12 months a year, many schoolteachers are paid ~9 despite being expected to work through them (on lesson prep &c).
It's possible to make low 6 figures, but a lot of pay is dependent upon length of time teaching and/or which district to get into. Good districts rarely have openings.
I'd say (not a teacher myself, but related to several) teaching is a lot more difficult than people give it credit for.
