This is a pet peeve of mine. Teachers are not somehow inferior to those who do. It's a completely different skill set that actually helps you "do" better.
Sure we respect coaches, but we also still in every sport pay them significantly less than the pros they ostensibly lead. I personally value both coaches and teachers but it's very clear that we as a people have decided that ability to do is more valuable than the ability to teach others.
Those who can't, teach
Those who can't teach, write
Those who can't write, write man pages
