Average Teacher's Salaries

Found this chart interesting in that in Luxembourg they pay their teachers (after 15 years exeprience) on average $90,000 a year.

It makes me wonder about the Luxembourgian education system and behooves a couple questions;

1. Do they have massive overhead then on "administrators" and "counselors" and "programs" and "assistant coaches" or do they just dedicate the vast majority of the money to (GASP) EDUCATION?

2. Do Luxembourgian children go to school, pay attention and pursue the sciences, or do they wreak havoc, misbehave, complain, and shoot their peers like their American counterparts while pining to go to college for "social work?"

3. If I walked into the average classroom, would their student to teach ratio be higher because (and I'm gambling here) the children ARE better behaved and thus it represents something more of an institution of learning versus a massive baby-sitting operation?

4. Since Luxembourg is a very rich country, they can afford to pay their teachers highly. So if we mimick their economy, teachers here could also get paid $90,000 per year. That would mean the NEA and teachers union would have to support free market, low-tax policies and capitalism that...oops. Never mind.
