The field of study of occupation licensing: https://en.wikipedia.org/wiki/Occupational_licensing

It's absurd to think someone needs to take a $1k 'Philosophy of Mathematics' class to teach 10th grade geometry.

> The philosophy of mathematics is the branch of philosophy that studies the assumptions, foundations, and implications of mathematics. It aims to understand the nature and methods of mathematics, and find out the place of mathematics in people's lives. https://en.wikipedia.org/wiki/Philosophy_of_mathematics

Considering that the primary complaint 10th grade math students have about math is often "How is this relevant to me and my life?", wouldn't studying the philosophy of mathematics help a teacher in addressing this concern?

i'm aware of that, but can you give me a concrete examples where teacher unions in minnesota are causing the problem of occupational licensing?
