There's a joke on MASH where Frank Burns is reading a medical journal and he says that the article he's reading claims that, for major surgery, a surgeon should charge 5% of the patient's annual salary.

Hawkeye and Trapper then threw magazines at him because he cared more about money than medicine.

But can you imagine a law that actually did limit major medical expenses to 5% of a person's annual salary? In today's world, that would be huge!
