Yes, most people like teachers. And it's logical why services with measurable benefits to individual well-being, such as teaching and medical practice, also paramedics, psychologists and all kinds of therapists, are generally regarded as noble, regardless how they are remunerated.
What strikes me in Ricardo's attitude (apart from his ignorance about teacher's job) is his use of "primary school teacher" term not as an accurate inference about anyone's way of living but as a derogatory label to down or ridicule the discussant he disagrees with. He's done it at least twice on this forum (to you herein and to Berg previously). As if teaching kids (as opposed to adults) would signify that a given teacher is as "retarded" as his/her pupils. That's why I gave hi\m a bait, so that he considers myself also retarded. If consequent in his opinion, he should think that I know no more than "little preaching". He should also think the same of Nick Kyrgios coming out to teach kids and to play tennis with them, having good time with kids & running his charity to help disadvantaged kids. Of course most of us do like Kyrgios for doing what he does here. But Ricardo should be an exception and should ridicule Kyrgios as doing "little preaching".
But I suspect Ricardo won't engage in this topic. His opinions are not well thought logical conclusions about the surrounding world, but an ad-hoc "little tool" to intimidate/bully others. Most likely he falls silent when his "little tool" misfires. Such "little tool" of intimidation would definitely misfire when used herein against me.
