According to BLS, median annual income for Registered Nurses is 81k, compared with 61-62k for teachers. Higher, but nowhere near 2-3 times.

The comparison here is so vague as to be useless. There are 4 categories of nurse, and I can assure you that A) a CNA and RN (let alone an APRN) are very different jobs with different requirements and wage/salary brackets and that B) K-12 wages and requirements also vary drastically.

A CNA (the second most common "nurse") most assuredly does not earn more than the average High School teacher, let alone one with any sort of seniority or departmental/administrative responsibilities. An APRN probably earns more than any blue collar field as it's a decidely high salaried white collar position.

Also interestingly, in Europe teachers usually earn much more than nurses.

Nurses make more than teachers in the US an average but it is much less than 2x.
