"It's a big club, and you ain't in it"
I'm not sure I agree with this. If our schools were 10x as effective and we produced 10x as many smart people, I think we'd be having the same conversation. It would just be about how hard it is to recruit people to teach quantum computer programming when you can make 5 times as much working in the teleportation industry (facetious example, please don't debate the physics of this).
The faddish education "research" stuff that ends up being implemented in schools and used as material for professional development is often on the level of bad pop-business books, for the same reasons that bad pop-business books are so common and so widely read, I suppose.
Actually it's kind of like pop-parenting books and bad pop-business books had a baby and that baby is education books. They are, in the lingo of our times, hot garbage.
Admin, principal through superintendent, are largely careerist political types with shockingly poor reasoning and critical thinking skills considering most of them have been granted a PhD—another problem: for a bunch of reasons including demand outstripping legitimate supply by a large margin and a whole pile of bad incentives, education degrees on all levels are about 99% bullshit and there's no shortage of morons who shouldn't have been able to achieve a bachelor's in anything running around with graduate degrees and an ego to match—so they're terrible at evaluating this stuff and quite gullible, while also being very certain of any decisions they make. It's a recipe for disaster.
