Would the same quality care be available to the average person under the current system?
"an expert opines"? Now, there is proof positive.
I have a little grand nephew who was born in Copenhagen. He was born with a condition that causes oxygen deficiency in newborns, and would have died had the hospital there not been ready for this unexpected eventuality.
Hospitals in Denmark routinely prepare for this condition, while those in the US do not.
The boy's grandfather, a staunch "Roosevelt sold the country down the river" kind of ultra conservative, told me that the boy would most likely have died had he been born here.
The boys father, a Jesus as personal god, very religious type, thinks that he was sent to Denmark as part of God's plan to save the child.
While I can neither confirm nor disprove the opinions of my relatives, I can confirm that a healthy little boy is now a part of the family, and most likely wouldn't have been under our "best health care system in the world."
My anecdote trumps yours.
