There is so much wrong with this. You cannot judge the class of teachers based on a small sample of your taste in women. You didn't actually communicate anything materially wrong with her. You listed a high income area to make us think teachers are overpaid but we have no insight by default into median income in the area or her qualifications.

Lastly its entirely impossible to attract better candidates without more money its just not how the world works.

For reference the median household income in san ramon is about 200k so 2 teachers would be below average. A cop with her experience in the same town makes 158k
