My best friends son is in his first year at Andover Exeter. His Chinese is improving dramatically, he has a better grasp of the Middle East situation and what Islam really says (and does) than most adults I meet. I rate his educaiton as excellent. Throw in the connections he's making and the great sporting tradition he's a part of and there is no way I could deliver 1/20th of that in the home.
Sorry but I just totally disagree with your thesis "If you love your kids you will home school them". For some parents, and some kids, that might be best. For others, not so.
How about the truely poor and ignorant. They have kids too. Can't you imagine knowing that your not smart enough to teach your kids everything? We're only two generations from sharecropping in the USA. It's going to take those families a LONG time to get their progeny educated if they don't rely on TEACHERS.
Anyway, this is so basic it's probably not worth discussing further. If you don't get that great teachers are one of the best things in many peoples lives (including mine) by now, you probably never will.
As for taxpayers funding schools, we'll here at FR we have a higher percentage on minarchists and libertarians and even old school conservatives who see that. Most people will not. (Sad, but factual.)
I rate my typing as poor!
