The sad part about eliminating shop class wasn't the various projects that would be proudly displayed and then forgotten, but that those skills were not even touched on.
I have joined my (professional) mechanic friends in lamenting the places automotive engineers put things and how inordinately difficult they made even simple maintenance as a result. I have to think if those guys had had to pull a few wrenches in their day, maybe it would not be that way, but in the interim, vehicles have become incredibly more complex, and just diagnosing the problem can be complicated by sensor or computer malfunctions, not to mention the common short circuit caused by physical damage to a wire somewhere.
So I can see where the blue collar jobs of the future might involve a substantial education, and development of skills as well. Perhaps some dirt under some fingernails would have had more people using tools instead of stealing them--or looking down their noses at the people who use them to make a living.
And it might restore a little bit of the pride people once took in their craftsmanship.
