I would love to teach. I am very good at it. But I am also an entrepreneur to the core and hate, hate, hate bullshit.
I am one of two engineering mentors for our local FIRST FRC robotics team. Brilliant kids fully motivated to learn. I love it. We've built a bunch of neat stuff. I happen to own a lot of nice manufacturing equipment so we've taken advantage of that with the kids learning such things are running CNC and manual milling machines as well as soldering SMT, using DSO's etc.
Anyhow, one day I get hit with this business of having to register as an official school system volunteer in order to be able to be a mentor for the team. Mind you, FIRST has no such requirements, this is the school system bureaucracy meddling with things.
What did it entail? Filling out a bunch of forms that nobody could email me. I had to go to the main office and get them. And then they need to do a full-up background check, blood test and other crap. The process takes months. Oh, yes, and I have to pay for it.
Being that part of my work is in aerospace there are certain things I just can't do, at least not without involving certain checks and balances.
I flat out told the school system folks to go stuff it. I further threatened to fully fund the robotics team myself and pull it completely out of the the school. FIRST does not require teams to be attached to schools, so, technically, we could run it out of my warehouse and we'd be fine. The school folks took a few steps back and figured out a way to allow me to continue to be a mentor (after two years of doing it) without red tape. I suspect someone is making money somewhere by having this team be at the school. We are required to have a teacher associated with the team (one who knows nothing about nothing). My guess is he is getting extra bucks for having his name on a list somewhere.
This is just one example of why they don't attract better talent. We could have a lot more engineering mentors in this team but everyone recoils at some of the red tape they toss in front of you.
I know I and other practitioners could be amazing teachers and sources of inspiration for students. Yet, none of us has any interest in dealing with bullshit. And the school systems are permeated by it.
I mean, imagine the idea of having someone like Elon Musk do a physics lecture at a High School even once per semester. Think of the inspiration and effect that would have on kids. The effect would be very similar if you had passionate practitioners, perhaps less well known than Elon, yet passionate about their work, contribute to the education of our kids.
Money, to some degree, isn't the problem or the solution. We just don't have a good system. Teachers could be professional "inspiration organizers" who pull-in from the local and distant communities with the goal of blowing away kids with the passion, wonder and possibilities of the subject at hand, whether it is music, mathematics or physics. That. Something even a little bit like that. Would be amazing.
