As a former teacher who is currently by all accounts a fairly capable software developer, this saying drives me up a wall. I took 2 years out of my life to work for almost nothing so I could share my love of math and programming with the next generation. That I eventually gave in and moved into software engineering to make money says far more about my lack of altruism than my competence then or now. But forget me, I taught in a cushy city post, I know some people in the peace corps (I taught abroad) who are still in the game, teaching math and English out in the sticks, sometimes having to build or maintain their own school buildings and learning the local language with no assistance. The idea that the defining trait of teachers is a lack of competence is laughable.
