When we were traveling in Europe, we heard the exact same sentiments that Bernie has stated. They laugh at us and can't believe we haven't adopted something they've had for decades. They do not understand how such a developed country as ours is not providing health care for all of its citizens.
But then again, as we all know, it has nothing to do with providing health care as it does about politics. I thought the video on Jimmy Kimmel pretty well describes the problems; Six of One - Obamacare vs. The Affordable Care Act - YouTube
When presented with the actual facts about the ACA with no mention of Obabmacare, overwhelmingly people are in favor of it, including politicians.
If they would take politics out of it, they might actually considering doing what's right for the people, which is what other countries have already done.
