This paragraph from The Guardian says it clearly. Every article on health care in the US ought to remind people of this.
"Like the US’s disturbingly profound poverty, its over-the-top mortality is not due to some technical shortfall or economic constraint. It is a choice. The United States is not only rich. It is better at inventing newfangled drugs and therapies than probably any other country in the world. What it is terrible at is ensuring that its people, even the poor ones, have access to the basic building blocks of a healthy life – from decent jobs and humdrum amenities like potable water, to access to health insurance."
