For whatever reason, high school and the clown college I went to actually did teach about personal finance some. I don't think it was part of the curriculum, but points were made. My high school business teacher was always talking about 401k.

After I left my parent's house, however, I have been mostly on my own. I had to set up bank accounts, get credit cards, get a mortgage, and buy cars by myself. These are things I didn't know anything about and as a result of my learing, I have switched banks 4 times until I found one that suited me well.

Well, anyway, I don't know where you learn stuff like that. I think you just have to pick it up by seeing how your parents and others do things.
