For instance, what other nations provide football fields and weight rooms and equipment for almost every school? And then there's fully-furnished gymnasiums. And don't forget the maintenance - all that is very, very expensive.
What other nations use full-sized (and hideously-expensive) school buses for almost every route?
What other nations require each and every public (but NOT private) school to take in every special-needs kids, like the medically-fragile Foster kids I've had for nearly 15 years now? When they do so, they also have to provide nurses, caregivers, equipment, special classrooms...you name it.
A lot of other nations require children to bring their own meals so they don't have to pay for cafeteria and staff.
And then there's one thing that America's schools are now having to pay to provide that NO other nation needs to: armed security guards...and sometimes even metal detectors. Of course that wouldn't have anything to do with the Right's fetish with guns-everywhere-all-the-time...of course not!
In other words, guy, if you want your schools to have all that, then you have to PAY for it. But if you aren't willing to pay for it, then we wind up with situations like Texas does where about 41% of schoolteachers have to take second jobs in order to make ends meet...which means that instead of staying after school to help kids who are struggling in class, much less working on lesson plans and grading tests and homework, they're rushing to get to their second jobs.
If you want first-class schools with all the bells and whistles I listed above, then you have to PAY for it. Otherwise, you're going to get sucky schools.
