I decided to do some research on a dentist. It takes 8 years of schooling at a cost of roughly $350,000 for the 8 years. The average dentist makes $124,000 - $202,000 annually. The career has the fastest job growth along with the highest pay increase annually. And the lowest unemployment rate of any other career. If they specialize then of course the schooling and cost goes up but so does their income. I know that it's expensive to run a practice.
