Do you think someone needs any education at all in a subject to each it? Do you think someone who has never studied calculus should be able to teach it?
Right, well here's the answer to the original question then. If you want teachers to be able to teach calculus, and you agree people should have an education in a subject to teach it, then you need the teachers to study calculus themselves, which they weren't necessarily doing, because they studied things other than maths, so you need to use more resources to have them also take calculus classes, so it costs more.
Apparently school districts pay teachers more who get a masters. But it seems that having a masters doesn't mean they are able to teach a single course beyond high school level.
Sounds like things are all messed up in what districts pay for. They don't need more money, they need to redirect what they're already paying for.
Can you teach freshman Medieval French? No of course you can't. If you had a masters would you then magically be able to teach freshman Medieval French? No. You just haven't done the subject yourself so you can't teach it.
You can't say 'you have a masters you should be able to pick it up yourself and teach it to these school children'. Can you not see how unreasonable that is?
Of course I do. I am just bemused by teachers having masters degrees yet be unable to teach any freshman college level class.

Freshman calculus is not rocket science, and I expect someone with a masters degree to be able to handle it.
