In 3 or 4 years of dedicated training (3-5hrs a week) one could start Judo as a white belt and end up with a black one. A few coaching courses later and they are ready to teach.
Now, here is my question: what is the typical rating of a complete n00b after 3-4 years of chess study? (to use myself as an example: been playing for 9 years and float between 17-1800 blitz on chess.com {My OTB is ECF:160}. SO 3-4 years is what? 15-1600?
and what about the guitar teacher you took lessons from as a kid? presumably, your teacher wasnt hendrix or halen, but a musician nonetheless that seemed competent enough at the time. Indeed, you learnt how to play, didnt you?
....If you think about the time required to study a disipline, it takes several times more effort to become a chess master than it takes to become a judo dan grade (I speak from personal experience)...but, and here's the kicker, the judo guy seems significantly more qualified to teach than a non-titled chess player, despite both having put the same amount of hours in.
....thus here is my point: dont underestimate the vast amount of chess knowledge non-titled players have. If it were any other disipline, they would be more than qualified to teach you.
The final thing i would say is that lower rated players should have a very different tone than than masters when they do decide to teach. Masters can afford to be a little more authoritive, the rest of us cannot get away with that. Thus, we ought to teach by posing questions, rather than claiming to have the awnsers.
I 'coached' elementary school children. But that was more like babysitting.
That sounds truly awful. Were the wages good?
