My first introduction to personal finances was because I sought it out while I was in high school. It was a simple pamphlet called One For the Money, that my church (of all places) published. It was fascinating to me. I could hardly believe at my young age that people could accumulate so much debt as to need special programs. I was surprised that high schools didn't teach the basics of money management.
I saw people all around me making poor financial decision early in life, setting patterns of behavior that would leave them in dire straits once the major bills of adult life came. Since most people get their education from learned behavior from parents, this is not a great scenario -- since many parents are no better off than their children regarding handling money properly.
