Pharm reps...when I was growing up, one of our family friends worked as a pharm rep. They were also known then as "detail men". I don't know if they are sometrimes known as "detail folks" now...
However, pharm sales are not the only place needing sales people. There are all sorts of medical equipment sales people. I did an observation in the cardiac cath lab recently, and there was a medical sales rep there who had been a Radiology Tech. She put on "leads" and came right into the cath lab just as though she were an employee there. She stayed and watched the procedure, waiting for the nurses to be done before making her presentation.
It sure didn't look to me like she had to work very hard. No malpractice insurance, either!
There are a lot of "detail men" who make more than many docs. A lot of primary care docs, after paying for their staff, their equipment and their malpractice insurance (which is frequently in 5 figures) make in the mid to low $100Ks. Please read that carefully...that is NOT the same as "low six figures." Recently, authors of the book "Critical Condition" were on NPR with Terry Gross and called what general practitioners make as "embarrassingly little."

Actually, of the last 4 days I've been in the hospital, two of the those I've seen sales people in the hospital talking to staff. The first day I was in orientation, and the other day I worked with agency folks because the regular folks were at an in-service.
