Here's the version of a lawsuit spread by the interests who want to protect companies and make it impossible for people to sue for damage:
There was a lawsuit in which a person using a pay phone was injured when a car went off the road and hit the pay phone booth, and they won a lawsuit AGAINST THE PHONE CO!
Sounds crazy, huh? We need to get rid of all these crazy rights of people to sue!
The actual story: the person in the phone booth saw the car coming and tried to get away, but the door was jammed - and the same thing had happened months before, and the phone company had been notified about the door being stuck, but had not fixed it, so they had a share of the liability. Oh, not so crazy. They didn't mention that.
Here's another. The version from the company protectors who want to end suing:
A woman went in for surgery, then sued that the surgery had damaged her psychic powers, and won money! Crazy, huh? Get rid of suing!
The actual story: She did sue for that - and for other errors of medical malpractice. The jury gave her zero for the psychic powers, but money for the legitimate malpractice.
Oh, not so crazy.
These things are propaganda put out by interests who simply want to take the power of legitimate lawsuits from the public.
The McDonalds example is just another that has a lot more to the story.
The system actually works quite well.
The threat is the political system when it's bought and paid for by interests, who use that influence to gut the protections for the public.
It can go both ways - if the trial lawyers get too much influence, they can get excessive lawsuits, but the much bigger problem is the industries gutting the right to sue.
That's not to say there aren't some areas of excessive suing - patent trolls are a good example.
