25. Dental Hygienists
We all go in for teeth cleanings two times per year (or at least we should) and often spend a good hour with the person cleaning the teeth. This is not the dentist, rather the hygienist. This person cleaning your teeth is happy to make your teeth healthy and clean and at the same time, happy when they get off their shift because they make $70,210 per year. Expect to see a job growth over 113,000 over the next decade and expect this career path to continue to be one of the best and most cost-effective around.
