You really come across as a smug snob you know OP.
I care nothing for your opinion. I only care about the opinions of people I respect. People who express opinions from a position of knowledge of the subject.
I dread to think how you act around kids from disadvantaged backgrounds, or with learning disabilities.
You are not very observant, I've said several times I'm retired. But the last years of my career were spent working with DCs just as you describe. I was very good at it.
I genuinely would hope you do leave the profession as the idea of someone so rude teaching kids fills me with horror at how horrible you might be to some of them who struggle.
I'm not rude to children. I had endless patience with them.
Stupid adults who should know better? Meh. Not really.
