It's worse with lawyers, in that mistakes they make can go unnoticed for years or forever, so bad lawyers can still bring in lots of money to the company that provides them to you. Or so I think.

And the same with doctors, unfortunately, when they don't meet the person they treated again, when there's no follow up if it worked or not.

Plumbers, though, are different, in that then there's more feedback: does the water pipe still leak, or not? So they need to do something that actually works.
