How much of that "money thrown at the problem" is actually used to pay teachers more and attract competent teaching talent and give the teachers proper resources they don't have to buy with their own money and providing needy students the help they need to succeed?
I already know the answer, because many in my family are lifelong teachers. All money goes to facilities that don't always need it, though are still good investments, and administration.
The current process sure works well to say "well we keep throwing money at it and nothing improves" as if you can LITERALLY just throw money in the general direction of the problem and see an improvement. As long as those prioritizing funds and resources continue to just ignore teachers wholesale, we will see no improvement in education.
