Well that can be a good start to inform people of what the market is and how it works. However, I think it's too early for it to be given such significance in such a way that you have to give it one subject at school. I think it's better if it will be incorporated in economics or business subjects for high schoolers because they can show more appreciation to things and topics like this compared to kids, who are not so inclined on this topic and should not be bothered by things like this because they are in the middle of enjoying their childhood.
