LOL...
My kids went to private schools (more than 20K a year) and academically it was worth it...
But as my son said 90% of his schoolmates tried drugs and they were all sleeping around... Especially the ones with very strict parents...
Of course the last to know were the parents...
Perhaps you need to be more selective in what KIND of a school it is. Ours go to a wonderful Christian school. They aren't hypocrites there. They live it and kids are actually HAPPY to have some rules and boundaries. They're secure and know they are loved.
Too bad about your situation.
