While the type of degree is important, the bigger issue is work ethic and spending time to master something. Not everyone is cut out to be a doctor(or any other high paid "path") and not everyone wants to be one. If suddenly everyone became computer programmers, the pay would fall for that as well. Then suddenly becoming a programmer would be looked down at. It's almost getting that way becoming a Lawyer. Unless you're graduating form a top tier law school, you're aren't seeing 100k a year. There are simply too many graduates and too few jobs.
Mastering a craft that's in demand and that you enjoy is key. The rarer the skill, the more you will be paid.
Maybe most important of all is networking. Network now before you need the job or clients so you will have people to call once you're ready.
It's not so much high paying fields as it is ones that have job openings. You have people who major in things like film and journalism and are shocked when they don't get jobs
For example teaching isn't "high paying" at all but almost everyone I know who went into education whether it be elementary/middle/High got jobs right off the bat.
