Something is Missing

I read this article in the latest edition of Army Times:

"In a Nov.30-Dec 2 Gallup/USA Today poll asking respondents to rate the ethical standards of people in different professions, 65% of respondents said military officers had high ethics. Car salesman and lobbyists came in at the bottom."

Here are the top five:

• Nurses 83%
• Grade-school teachers 74%
• Druggists/Pharmacists 71%
• Military officers 65%
• Medical doctors 64%

Do you notice anything missing from this list that should be there?
