The US Healthcare system is shamelessly intertwined with the state to limit supply and extract rent.
Try to open a hospital and you will run into certificate of need laws who's primary objective flys in the face of supply and demand:
> A primary objective of state CON laws is to control health care costs by avoiding unnecessary expansion or duplicative services within an area.
Or simply try becoming a doctor in America; also known as assuming half a million dollars in debt and 8 years of college education and another 4 years of 'residency' a program where you work yourself to the bone for peanuts. All this courtesy of the professional organizations getting in bed with the state to limit competition and enrich themselves.
Let's not even discuss the pharma industry :).
Any discussion of bettering healthcare in the US that doesn't take on the rot at the core of the system is dead on arrival. Switching to a public solution tomorrow would just further enrich the cronies at the cost of the general public - and health outcomes would be largely unchanged.
