That is not an argument, it is an assertion that offers no real explanation whatsoever. An argument would connect who is paying to the high prices, this article fails to do that.

The 18% overhead of insurance companies, just like the overuse of care argument rebutted in the article, does not explain the high relative cost of care in the US.

Of course it is part of the explanation. That administrative overhead — the bureaucratic army it pays for and marshals as a lobbying and negotiating tool — encourages hospital monopolization, which gives providers greater bargaining power, driving up prices.

Yes, but per the article itself it only explains 18% of cost. And overhead is never going to be zero, so you can maybe, what cut that in half? At best? That's not even close to explaining the discrepancy between US per capita spending and other countries.
