It's no surprise that this made the top 10. After completing four years of an undergraduate program, four years of medical school, and up to eight years of an internship and residency, doctors receive fantastic job prospects and, of course, impressive pay. Doctors of internal medicine, or those who diagnose and treat diseases and illnesses, made an average salary of $188,440 in 2013 and a median salary of $186,850. Plus, the unemployment rate currently sits at a very low 0.7 percent.
