I'm sceptical, isn't the take from this we should have that we need to improve the education needed for educators. In my childhood, the only teachers that did not make life hell for me where the ones that actually had decent education, and was not just extra hires.

That's literally the opposite reading? The teachers who got better education didn't perform that much better, so the education needed does not need to improve. Based on that article the argument would be "if you want to raise the bar for teacher education you need to improve the level of what and how it is being taught".
