You are pointing out exceptions rather than the norms. Do not cherry-pick. I'm pretty confident that most people in these threads are thinking about computer programmers, white color jobs, and blue color jobs. Things that
don't obviously need a degree.
Depending on the type of nurse, you do not need a degree. Some will need to pass an exam though. You can become a lawyer without a degree, only needing to pass the BAR. An engineer doesn't need a license. You are thinking of a Professional Engineer, which is a specific job title that has legal ramifications. This requires a degree but it also requires you working under another PE for some time and then passing state competency exams.
The cases we're talking about here are jobs where if you do something wrong you can kill hundreds or thousands of people and destroy millions or billions of dollars worth of assets. *You've just completely moved the goalpost to try to make your point.*
Do you really honestly believe that these jobs shouldn't require a formal education?
I'm not going to take anyone seriously that is going to argue that medical doctors shouldn't receive formal educations. Come on, don't be dumb. Just have a normal fucking conversation. You don't have to double down and back yourself into a corner.
I know you're not that dumb, so stop bring disingenuous.
