Politicians shouldn't be paid more, they should require industry expertise and have a term limit of 4 years. You work in industry, you become a politician, and then you go back to industry.
The revolving door and regulatory capture are the real issues.
I'm talking more about congressional representatives.
It's likely beneficial for doctors to be intrinsically motivated to heal people, but regulatory mechanisms shouldn't be built on the assumption that it is the case.
Or is the idea that motivation is more important than relatively objective measures of effectiveness?
As for curing diseases, I can’t imagine why anyone would care why someone developed a cure. As long as Doc saves my life, I do not care if he did it for the money or for the feels or because he had a weird fetish and liked the shape of the mole on my rear.
