I keep waiting for someone to write a book about how often this is the case in different industries, areas of expertise, etc. It's a variation on the George Bernard Shaw thing: "every profession is a conspiracy against the laity".

In my own profession I'm extremely wary of my peers and the services they provide for the simple fact that I know how much and how often things can go wrong, and when I've needed those services myself, it takes me a very long time to vet people.

"People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices." - Adam Smith
