I agree with you but it's not that simple. John Taylor Gatto doesn't think the current school system can be salvaged, and he should know. Read his book The Underground History of American Education online.
As I see it, all Christian parents should yank their children from government schools. According to Gatto, government schools only provide a slaves education. If you want more for your children, send them to a good private school or homeschool.
This was just posted on another thread, it's a history of US public school education, and the quotes posted were an eye-opener.
