Although higher education has been active in promoting their own belief that a degree should result in a job. Perhaps that was a mistake and needs to change....except that it's already too late. Due to computer literacy the whole world of traditional education has changed. I doubt it will be changing back.
The trend to computer modeling and 3D printing and local Maker-spaces will allow the garage hobbiests to compete at the same level as the big manufacturers. And open forums allow for builders to exchange tweaked model files. Maker-spaces in (increasingly) every town allow the hobbiests to build each others' motors and test them out.
Where the formal training and certification can come in handy is when it is required to not only show that it works, but why it works how it does and at under what conditions it will cease to work as expected. And to prove it to the payor/owner.
Yes, I am one of the "old style" guys who does it all: the machining, welding, working drawings, and assembly as well as initiating the design and engineering analysis. As you point out, at one time it wasn't considered all that unusual. These additional skills are enjoyable as a change of pace, they are neither difficult or time consuming to acquire, and are available to everyone. You might just mention in passing to your engineering students that the engineering analyst who also has mechanical skills won't ever have to worry about finding or losing a job. That person will enjoy a world with many more opportunities than applicants. And the pay is better, too.
The satisfaction of watching your model work on screen pales in comparison to seeing the physical object do its thing in front of you.
That said, someone with good 3D modeling skills can work for clients anywhere in the world, preferably from the comfort of one's boat, at anchor somewhere in the south pacific ;-) Just sayin'...
