IF YOU CAN, DO. If you can't, teach. If you can't teach, teach teachers. Back when I was an undergraduate, that was widely quoted in the STEM departments I inhabited.

Full disclosure: My wife is a retired school teacher. She taught all primary grades, in three different states, over a 20-year span. She was widely regarded as an excellent teacher. She did not graduate from a College of Education; instead she obtained a teaching certificate when she realized her first degree choice (social work) was a scam.
