I'm not very young, but I'll say that it was not taught at all to me growing up - not by schools or family. It should be. What little I know, I picked up mostly on my own. I had an advisor for several years. He was expensive (mostly because of the companies he worked for), but pretty honest. He taught me not to be afraid of stock investing, which has turned out to be mostly good for me. I also learned that having an advisor is ridiculously expensive, so I now I just do it on my own. I keep it very simple. The Bogle book was very instructive and I think his ideas would work for most people.
