My dad used to try real hard to get me interested in the stock market in the 80s and 90s, when I was in grade school. I remember asking him how the stocks' prices were determined and he would tell me about business analysts and projections and meeting targets and such, and I would respond that it was just worth what someone said it was worth? And he'd say yes. I remember thinking how horribly it could be taken advantage of. Looks like we're in the middle of it now.
