Okay, now I'm having trouble understanding you.
Would the students whose parents don't pay property taxes (or pay low amounts of property taxes) not be able to go to school, if their parents couldn't afford the tuition?
I live in a rural state with many bush schools. The feds are currently working with my state to provide a general test for long time teachers rather than specialized certification. Future teachers will require certifications in specific areas. Doesn't surprise me though, making changes already; all the politics corrupting the system.
We just had a family bring all their kids back into the school system. They didn't pass the benchmarks. I see many homeschoolers abusing the system, unlike the dedicated people on FR. That is why I believe eventually there will be certifications required for everyone. I'm sure you know and have witnessed what I'm talking about.
