I'm not sure we read the same parent comment. There is almost nothing in there about emotional intelligence beyond learning self-regulation, but emotional intelligence is at least as much about understanding others' emotions, understanding social cues and etiquette. But the bulk of the parent comment is about adaptability, general self-awareness and self-examination.

You then make an argument that education does, in fact, teach those critical skills indirectly through basic subjects. Having given such a bold premise, you would need to back it up with at least some supporting evidence. Given that you provided none at all, you shouldn't be surprised that no one sees reason to agree with that premise.
