We still have to aim higher than simply "it's free".

Over here in Montreal my GF and I have been waiting for a family doctor for already 3.5 years (took us just 1 month to get one back in Winnipeg).
The one time we had to go to ER, for a snowboarding head blow with concussion symptoms, we had to wait 13 hours on a quiet night because the night shift had only 1 doctor, in Montreal's 2nd most central hospital (Notre Dame). In fact, on average 12 percent of all ER visits in the Grand Montreal area end up leaving in frustration without being seen by a doctor.

Adding to the ER burden, walk in clinics no longer exist; you gotta use an online appointment finder, and finding an appointment often involves clicking on the search button for over 1 hour, fighting for elusive cancellations with many other people in the same situation.

Many countries have proven socialized healthcare can work very well. Spain, Israel, Italy, Germany among them. We gotta compare ourselves to them, no the US.
