These are not accidents though.
For example in Puerto Rico there was a good, affordable public health care system many decades ago (El plan Arbona). This was meticulously dismantled by the insurance industry through political lobbying and support of insurance-friendly politicians. Now they have the same debacle as in the US, sky high insurance profits and terrible health care. This was very intentional, not an accident of history.
