I don't think you need someone amazing at maths to teach kids. In fact that would probably be detrimental for most kids. I don't say that teachers don't provide much value because they're useless, but because they are usually very generalized and most kids don't seem be to that interested in learning. Even if you fix problem #1, you haven't fixed the arguably bigger problem. I also don't think that significantly increasing the quality of teachers would change much for most kids.
