Agree it sounds a bit yucky, but as a counterpoint:

I've heard so many kids talk about how they want to become youtube stars. They believe that if they only had the time and support, they'd be making thousands of dollars every day by talking into a camera.

So kids may already be considering launching businesses: in spaces with high competition, oversupply and poor business plans. I suppose this is nothing new: in my generation everyone was going to be a professional musician or video game designer.

I feel like teaching kids the importance of designing for a market, seeing what you can sell and getting real customer requirements could be valuable, but probably more worthwhile for kids over 10 or so.
