This is a hugely underappreciated aspect of why the cost of health care, including insurance premiums, is so high in the US. Well-meaning folks have called for decades for the US to transition to single-payer, citing the overall lower cost experienced in other countries as a primary motivator. Meanwhile, US companies remain the global leaders in the development of pharmaceuticals and medical equipment. That development is often subsidized by US taxpayers and the remainder is largely recovered from US patients because the single-payer systems in other countries often impose price controls that largely don't exist in the US.
(This is not meant to argue against single-payer in the US. All things being equal, a single-payer system would likely solve many more problems than it would cause. I'm just pointing out what many before me already have about how Americans disproportionately subsidize the development of the healthcare the rest of the world benefits from).
