This is always a common rebuttal but I used to work in education and believe me there was not a bunch of new money coming in. Quite the opposite. Maybe the data shows funding going up but that money is not making it to the students.
The amount of school administrators and non-teachers have increased at 10x the rate of teachers relative to students since 2000. I have no doubt funding keeps going up but virtually all of it is diverted away into bureaucracy.
So if you agree that administrators in public ed are doing a poor job managing the resources allocated to them, do you support school choice efforts that will allow more competition from charter/private schools that have incentives to spend more wisely?
Why would private schools be incentivized to spend more wisely? Why would paying a CEO obscene amounts of money to lobby for public funds be better than fixing public schools?
Because wise spending results in making more money.
