Once a high school student gets a job, they are in business.
Why not take 45 minutes out of their day and show them how business works?
Universities can show people how to split atoms and transplant hearts, but it is too difficult to show people how marketing, finance and operations fit together?!?! That feels like intellectual malpractice. It can be shown on a restaurant place-mat and is suitable for coloring. It is pretty easy (not that hard).
