There’s nothing worth saving and more money just makes it even worse. The districts are incompetent, the school administrations are wildly incompetent and the teachers union is just ridiculous. There’s nothing in the public school system worth working on. Homeschool if you can or do your best to budget for private school.
Edit: my wife is a HS teacher of 15 years. Her and many of her teacher friends are leaving the industry. It’s just not fixable.
Think about it like work. A low level manager or individual contributor may be able to greatly change trajectory and outcomes for their small team but is unlikely to change anything for an entire global organization and the bureaucracy that comes with it. With enough successes at a low level then maybe those get recognized and the effects begin to trickle up. Or maybe not but at least you did the best you could for what you were directly responsible for.
