The Best Health Care in the World?

According to Glen Beck:

"...America has the best health care system in the world. Is it perfect? No. But it's still the best. Yet we're about to throw it all away in favor of... government-run health care..."

According to David Frum:

"...Rarely are the American people reminded that we have the highest cancer survival rates in the world. That success is the product of an entrepreneurial spirit, something that Obamacare and its drift toward government control will inevitably weaken. There is little compassion in giving grandma access to a procedure while making that procedure half as likely to save her life; conservatives should say so."

And Flocke thinks:

Conservatives should also note that Grandma has a greater life expectancy in 38-47 countries - most of which have universal health care coverage.

America's life expectancy is ranked 49 th in the world according to the CIA World fact book and ranked 38 according to Wikipedia.

Why does America's life expectancy rank so low - below even communist Cuba?

"Which grandmas" are going to benefit from these excellent cancer survival rates? The grandmas under 65 among the 30-40 million uninsured Americans? Do these grandmas represent America? Are there Hispanics, Blacks, and Asians among them in equal proportion to the population of the country?

How does the "best health care in the world" translate into one of the lowest life expectancies in the industrialized world?
