Sometimes, you have to get in their face. I've never been rich, but I get excellent health care these days because I refuse to let doctors bully me.
The magic words to get better medical care are:
"I feel like you don't take me or my health concerns seriously. Will you please listen to me, and not act like I'm a hypochondriac, or a nuisance to you?"
"I think it's time to contact my insurance company (or Medicare) for a new doctor, because you don't seem interested in treating my condition(s) or addressing my concerns."
And the nuclear option after finding a replacement doctor:
Reporting the jerk doctor to the state medical board for whatever reason you found their care unacceptable. Lawsuits don't scare them as much as complaints to the medical board, because the latter are something you can do to stick it to them at no expense to yourself, unlike a lawsuit.
The first thing you need to do when you get a new doctor and you're anywhere you can see his actual license? Get the number of the license itself. It's always on there, in case you need to teach the doc a lesson he won't forget anytime soon. I find that any doctor who keeps me waiting in an exam room where his license is hanging long enough to get the number off it will be a top candidate for a medical board complaint. Funny how that works.
Notice that I don't mention pursuing lawsuits, because that's an option for rich people who can afford the legal fees if they lose, or won't get worn down by the doctor having better lawyers who drag things out until you give up because you're almost bankrupt from lawyer's fees. I've never been rich enough to pursue that option. But I've never had to. Most of the time, I don't have to get past stage two to get them to stop jerking me around. But I have done the nuclear option on a couple of occasions, because the doctors were that awful.
