Sorry but this list is complete BS! Pretty much everything Rushrhee said.
No way Dental Hygienist and Chiropractor should be anywhere in that list. And for the Occupational and Physical Therapist is confusing as well. Most PTs and OTs go to school for 3yrs and they NEVER make over $95K a year and it is really a boring profession from the people I have spoken to that are in that. I know doctors that say that the ONLY profession in a medical type field that they would tell me not to go down that track is PT, they just say they don't know a PT specialist that actually loves their job...and their pay.
Even Optometrist is in the same boat as podiatry b/c their is such a small amt of practices that actually practice that.
And a university professor is a good job...after you get tenured. Until then you don't have much of any stability to keep your job and most of them need a second job if they only teach one or two classes per week.
I really don't think they put much of an emphasis on $$$$ for this list. Some of these jobs high on the list are mostly low paying jobs that are fun, but in today's era you can't just have a fun job with a $60K job. Just my opinion
