Interesting post here.
I retired this year after 45 years in either manufacturing or mechanical design.
High school plus 2 years of community college.
When I entered the workforce, I already knew how to work with my hands and repair engines and perform auto repairs (thank you, Dad!). I fell into a great career in precision sheet metal in the Silicon valley just as the electronics boom got underway.
I could see right away the place to be was programming the turret presses which at the time was done with a Teletype and paper tape. This was the beginning of those "digital skills". After several years of staying on top of the latest programming software I was able to go in the back door into CAD design .
I ran into millinials in the last few years who were dedicated gearheads, good with working with their hands, and extremely sharp in their fields. I had dinner on a business trip in 2012 with an Israeli twenty something who designed and built his own dune buggy with a welded steel tube frame and a Subaru powertrain. That was impressive!
But they were in the minority.
What works against them are, in no particular order, are a lack of vocational programs, lack of parental training, fewer manufacturing jobs, or working in places that don't allow advancement, and a general lack of understanding about what it takes to design, fabricate and refine things, and the myth that everyone needs a college education to succeed.
It was my embracing of digital skills early on, a healthy dose of mechanical aptitude, employers who allowed room to innovate and expand your talent, that allowed me to have a lot of fun during my career.
