There is an analogue to this in manufacturing as well. We lost something when we moved all of our manufacturing to whatever the race to bottom place was of the moment instead of understanding how to make our things from top to bottom.
Woodworking, shoemaking, metallurgy, even services like plumbing or an electrician are getting harder and harder to find. Building and repairing electrical machines. Refinery of oil-based products. Manufacturing of computers and circuitboard beyond the most basic.
There is no manufacturing sector, anymore. It’s all gone.
Tangential anecdotal point: I used to have an antique "home improvement" book from 1910 or so. The exquisite wood joinery that was shown there (as the achievable standard for the motivated man-of-the-house) does not exist anymore, it’s not being taught.
