Argh. Again, a complete misunderstanding of what a University does. You do NOT go to University and get a degree in welding or truck driving.your degree has an expiry period
Universities do NOT provide vocational training. If they do, they really aren't a University - they're a community college that's pushed some paper and is fooling their students.
You don't get a degree to please anyone else. Not a fat cow in HR, not a shop foreman. You get a degree for YOUR benefit.
I don't know how to explain this any better.
I did an engineering degree. I was really good for me, I think, but did it make me more employable as a pilot? Nope.
If all you want to do in life is weld or operate heavy equipment like a bulldozer or an Airbus, a University degree is not the vocational training that you require, to do so.
