This is true of the service industry in general. Anywhere there's expertise contrasted with public ignorance, you'll probably find folks who want to make a quick buck by capitalizing on it. My two main fields (cars and computers) are rife with this sort of corruption. It really angers me that people would abuse their position like this just out of laziness and/or dishonesty.
