Rationing of care already happens to some extent, even in private insurance plans. We see it when what we need is called “elective” or “higher standard of care than provided”. Remember when you could pay a little more and receive a private room in the hospital. Wave that one good bye. And in the past, a person can always elect to have medical care outside of their plan and just pay for it. Tata to that as well.
If it's not good enough for our senators or congressmen, it's not good enough for their constituents!
