Not with a grain of salt...but not God's word either. You know how statistics work, and how difficult it is to get the numbers right. So there's dispute and always will be. In science they have a name for this phenomenon - experimental margin of error.
However, I wouldn't take that 75k example as typical. It defies common sense.
my brother-in-law is an adminstrator at a large hospital and they don't turn anyone away
No hospital emergency room anywhere turns away anyone. It's the law - Hill-Burton from the '50s and other stuff subsequently. But that doesn't contradict my statement about people suffering from lack of medical care. Showing up indigent at a big-city emergency room is no fun...and a lot of people didn't know you could do it. As the knowledge has become more widespread the pressure on hospitals has increased. At first, governments covered the shortfall with taxes but now - as that's becoming impossible - more and more hospitals are closing.
There is a model of how healthcare should work. It is called cosmetic surgery. Since insurance companies usually don't pay for this, it is handled on a cash basis, for a fixed fee. There is an actual market system for plastic surgery and things like laser eye correction. Since it is a capitalist system, it is both affordable, and good quality. The problem with the rest of the healtcare system is that the gubmint has mucked up all financial reality.
