It sounds like a project manager is a highly skilled individual with many years of experience, leading a team to meet specific goals for a company.
Can one actually earn a degree in project management?
Don't know for sure; a quick search could uncover a lot...
However, I would think a business/management degree at many schools would include courses in project management, to include tools such as Gant charts, etc
Yes... it is not an easy field... but very well compensated
You can get PMP certified, get as many management certifications as you want. Could get you an entry level job, but like anything else in this world that is worth doing and being good at, it takes years of experience, I detected a hint of whimsy and sarcasm in your post, so I suspect I’m not telling you anything you don’t know already 😊.
