Honestly, I think this is not true, in my experience at least. I think suing doctors was a feature of the '90s and early 2000s, but now people are so poor they can’t afford lawyers to sue a doctor for them, and medical malpractice runs so rampant that doctors don’t even seem to care at all. Everyone has had a bad running with a doctor, yet you’re very unlikely to hear of someone who has sued a doctor and gotten away with it.
