Won't become a billionaire in those jobs. Can't even get professional pay in many of those roles today with workers from India and Vietnam competing for the same positions.
Nope. Entry level people can't compete with H1B workers willing to cut their throats at 30c on the dollar. Kids are getting sacked the minute they step out of school.
If I was going back to school right this second and had to recommend a profession, I'd do something in health care (lots of Boomers aging out) or a trade like electrical or welding. No outsourcing those fields overseas.
