Of all jobs, being a doctor usually pays the most money. The Medical Group Management Association's Physician Compensation and Production Survey says that most doctors earned between $132,953 and $321,686 in 2005. How much they earned depended on how long they had been doctors and where they lived. It also depended on how many hours they worked and how good a doctor they were. And it depended on what kind of doctor they were—specialists usually made more than general practitioners.
