>These are very hard questions, and it’s frustrating to read the phrase “we need to fix the system” because yes, obviously we do, but agreeing that things are bad isn’t the hard part, and probably input from people who have never worked in the field is of pretty limited value in how to resolve the hard part, and will not do much more than annoy teachers even more.

I don't agree that the system is broken (broken to me is something that is completely unusable, and we must stop using immediately). The progress we've made as a global civilization is to be credited to the way human knowledge is captured, distributed and taught by us as a species. And certainly formal schooling is a big part of that. And so, I'd rather view the situation as us being on a path of continuous improvement - where everything, including education can be improved.
