That's because you're an anesthesiologist, and you see the acute cases which have already been admitted to the hospital. Poor people don't receive comparable long-term care. They don't receive comparable followup care after procedures. They can't afford lifesaving medication, they can't afford physical therapy, and they can't afford psychiatric care. They're denied for transplants, and many surgeons won't accept them as patients because their recovery stats are so much lower due to the aforementioned lack of followup.

All of this, without even mentioning the increasing number of specialty surgeons that operate on a cash-only basis, or the poor who don't go to the doctor simply because they cannot afford to. There's no comparison between the care that the rich and poor receive in this country, except possibly once they're unconscious in the OR.
