Earlier quoted context omitted.
Although I agree completely, that's a very high expectation of teachers (pre-college) for the amount they get paid.
That's a really sad comment. Teaching may not pay well, but the tenured teacher has significantly higher job security and potential for other incomes. Yes, it's not a typical programmer pay, but if you are taking it upon yourself to teach children, you take on far more responsibility than any pay can justify and you should act like it.
programmers also have job security of knowing they are basically always employable right now unless completely hopeless. and programmers have ethical responsibilities which are frequently ignored too.
