There is a disparity. It's linked to parental effort, not wealth. Sure wealth makes it easier to get tutors and such, but primarily kids who excel have parents who read to them and worked with them on homework. And teachers benefits outstrip almost any other job. Far more time off, pensions, good healthcare, etc. It's not a problem of what teachers are paid (there is no teacher shortage), it's a problem of how they are managed. Limited competition, degree and seniority driven promotion, tenure, etc. But again, the best teacher in the world is going to struggle if their kid's parents don't give a crap about working with them at night.
