The American education system seems to have taken a serious turn for the worse in the past 30 years, but when I was in junior high we had a class called Industrial Arts, aka "shop class". We made stuff, using real industrial processes including things like injection molding, on real equipment. High school offered more variety and specialization, including wood shop, electrical shop, and auto shop.

But we're far away from that world, and getting farther. There's a good chance that by 2030, 3D printers and CNC machines will be considered "firearms" for federal regulation purposes.
