Overall I'd say it was at least billions... probably, over time, it has been trillions that have been wasted. Too often we see the "it's for the kids" mentality that throws good money after bad into the pit of despair that has become the larger portion of public schools. But heck, we can't even suggest modeling it after far more successful programs elsewhere... what would happen to the teacher's tenure?!!!
Some Charter schools are unsuccessful, so the Democrats' mentality? Close them all! Don't take the good ideas from successful charter magnet schools... Don't even suggest that!
If the vast majority of charter schools can't replicate what the successful charter schools are doing notwithstanding the general freedom to operate that charter schools have as compared to their public counterparts, why is is reasonable to think that public schools can replicate those successes in a much more confined operating environment (and with substantially different student profiles)?
Also, too, charter school advocates would be wise to weed out the grifters in their ranks.
