What is the most distrusted occupation on the planet?

This question came to me, after a discussion with my wife about people she distrusts, because of their occupation. New and used car salesmen came in first. Politicans came in second and attorneys came in third, according to my wife. These were her choices based on past experiences she has encountered with all three. Question: were my wife’s choices accurate? Or, are your experiences somewhat different and please give some examples as to why.
