I'm not sure how this is the same, honestly. I'm assuming most of the folks that left went to more expensive places, but got higher salaries, too? Many probably left to go where they feel they have a better chance at building a family?

Such that, I'm not sure how this works. They should count their luck that they have you happy to be there. But luck only goes so far. Or are my above assertions wrong and you think the people that left made a wrong choice for them?

And my assertion on the cost of education is a bit more nuanced. Specifically, I posit that if you transplanted the teachers from the good schools straight into your school, grades probably would not change. It takes more than just the teachers. Even transplanting the administration would likely not do much. The low performing school doesn't need the same level of skill as the well performing one. It needs better. And more.
