Given that many actual 3rd world countries have health crises that are far more severe than anything in the United States, I really don't find the comparison very tasteful. The financial element is absurd and no one will argue that the American healthcare system is optimal by any means, but you really need to travel more if you think that it's categorically the worst in the world.
I agree that privilege plays a big role in shaping one's perspective on this, and to that end, again, you should travel more if you can.
