Of course it's shared by others! The “free market is the solution, stupid” political stance, is one of the most common tropes of the [American] conservatives.

The fact that American life expectancy is due to “cultural differences” is unsubstantiated, the fact that with health insurance, the US health care system is the best of the world, is also bullshit. Same for “the US subsidizes health R&D for the rest of the world” (this is true for “neglected diseases” though, but because of philanthropists, not because of the domestic healthcare system). And I'm not even talking about the fact that “lack of insurance could be solved by UBI”!

It also fails to realize that “competition” itself often adds more costs than the efficiency benefits it provides, because of fixed costs (each private insurance company share the same set of administrative costs), because customer acquisition leads to big marketing spending, and because competition can drive salary costs up for jobs with limited supply (physicians here), because the competition is also at play when hiring.

But the free market enthusiasts don't really care about facts, free market is a religion and all I said is blasphemy.
