It has contributed to a great many parents deciding that they have had enough of this nonsense and pulling their kids out of public schools.
Back when schools were local controlled parents had the happy illusion that they were in charge of their child's public school education. They were not. The arrival of the DoE forced them to face that truth and react accordingly.
That was probably not what you meant by public good but tearing the mask off was a good thing.
No, that is not what I meant, but it’s a good point.
