No, that one definitely is true and contributes to the massively more expensive healthcare in the US.

Exhibit 6 confirms your pharma isn't just more expensive, you consume more of it- but compare last equal NZ's overall cost to see how the US cost is racked up. Exhibit 7 shows that US price for MRI scanning is not so different from others but the price for procedures is far higher - e.g. the price for a bypass procedure in the US is twice the cost in wealthy Switzerland- and the price for pharmaceuticals is twice that of Canada or the UK but only 20% more expensive than Switzerland with all its powerful pharma companies.

Also worth reviewing Exhibit 9-13 showing that despite spending the most, the US comes last/does badly in a basket of outcome measures. Interestingly, only NZ is worse than the US for ischemic heart disease mortality, but mortality is a tough one as we all die in the end(!) so you need to consider whether that's tied to reduced longevity (Exhibit 9)
