But what people can afford.
My company--I own a piece--provides its own coverage and it's made clear to us that the cost will depend on our choices. So for example we have rules in place that for non-emergency treatment in an emergency room will not be covered to encourage use of lower quality and much cheaper medclinics. The care is good enough and keeps costs down.
Agree with Peter on the good points and getting healthcare out of the hands of employers.
It would make business more competitive.
Which would drive innovation and force prices down, in the video, iirc.
