I'd love to see the list of people you surveyed to draw this conclusion. In my metropolitan area availability is abysmal and (in my experience recently) quality is not great. I am contrasting this to my recent experiences in the US system.
If you are one of the lucky 10% at the top of the heap US healthcare will outperform.
Edit: what, am I out of touch? Is health insurance only provided to employees in the top 10%?
I think you're being down voted for the 'generally affordable' and 'bankrupting illnesses' parts. "Middle class" doesn't usually equate to tech level salaries or benefits. Family health insurance can be very expensive for middle class families. The extremely high family out-of-pocket max plans can turn even non-catastrophic illnesses into a financial crisis.
