I can see Medical Degrees and Legal Degrees.
Isn't the rest just "training".
There are definitely places where degrees matter. For example, EE and CS degrees make a lot of sense for folks that are designing CPUs, programming languages and such. OTOH, a CS degree does NOT make someone qualified to be a programmer - or any other role in the app dev cycle.
Another example would be something life wildlife biology. A degree certainly helps somebody figger out wildlife habitat requirements and such, but the degree isn't necessary for people implementing practices designed by somebody that has the degree.
The ONLY reason degrees are required to the extent they are today is that more and more people have them. IOW, employers require degrees because they can. Just another data point to thin the herd of applicants.
Somebody mentioned Graphics Design. I can see where a degree, or a very lengthy and detailed course of study would be a huge benefit for Graphic Designers. Same for Marketing types. There is a lot of fuzzy knowledge required to be the best at getting people to use their plastic.
Any of the arts are served well with degree programs. Big difference for trades and technical though. They don't need to figger out WHAT to do, they need to know HOW to do it.
The numbers of lousy administrators and managers tells us how well served those particular roles are served by the secondary education system.
