teachers salaries: public vs private

There was an interesting quiry on Park Slope Parents this month about teacher's salaries. It is a bit of an apples and oranges conversation. I have some links if you want to do more reading. It appears that public school teachers win out pretty clearly on salaries and benefits, but private school teachers may have some quality of life benefits (smaller class size and no state testing requirements). Both jobs are very challenging (no one has it easy!).
Here are some links, but you need to filter out the politics (right wing, anti union; left wing, pro union, etc.)
