Let me go on record as predicting that those joining and those not joining will exhibit no statistically significant change to whatever trajectory the affected students are currently on. It won't make any difference.
The total tax bill at the local, state, and federal level to support K-12 public education in the US is $500,000,000,000.00 per year. Five hundred billion dollars per year, and for what? If any other American institution had such a gargantuan budget and produced such a slipshod product, its executives would be shown the door or brought up on charges.
The people in charge of this institution are incompetent charlatans. It is just another distraction created by people who don't have a clue of how to get students to learn.
