Have you actually talked to anyone from those countries? Have you talked to the ones getting their free healthcare and the ones who are paying way more that others? Have you talked with the ones who are just getting their little boo-boos fixed or the ones waiting months and maybe years for major surgeries? 
I don't know about you but I just as soon not have the same entity that has failed our veterans healthcare, and runs the corrupt and heartless IRS in charge of my healthcare. 
Just remember everyone of the polls results are coming out of the WHO and they are about as dishonest as they come.
