Thinking back to my own religious high school education, I realize that the ethics component (though never called out as such, it was woven into the curriculum at every level) was indeed important; not so much because of the specific rules they taught and didn't teach; as simply in teaching me that ethics and morals were something to think about and discuss.

Then again, this was a Jesuit school; and Jesuit education has a reputation for being somewhat more Socratic and questioning than the typical deontological viewpoint of many schools.

But in any case, yay for personal finance.

It might be possible (and useful) to design an ethics curriculum that helps students to think more clearly about their own views, though, without giving their teachers much of an excuse to preach.
