Why do most people hate lawyers when they don't have need of one?

Why is it people want to hate lawyers when they don’t need one, referring to them as ambulance chasing, blood sucking soulless vampires, etc? People love to hate lawyers when they don’t need one but when they do they want the best lawyer around even if they can’t afford him/her, and want that person to be a regular prick, a pit bull in court, someone with ice water running through their veins. Lawyers get paid what they get paid because we the people decided to allow politicians most of which were lawyers to set up the rules governing society in language only lawyers can understand so when legal issues come up we have to hire them to interpret what our rights or benefits are. I don’t know many people who would want to go into court representing themselves if they don’t have to.
