Having universal health insurance available for everyone is a consensus opinion in Germany, no party disagrees with that. In the US "socialized medicine" is a controversial topic.
And at least in Germany I don't see anyone questioning universal healthcare. There are of course discussions on the details, but nobody is trying to abolish it. And while there are inefficiencies, the US health care system is even less efficient. So we would not save any money by making our system worse.
Therefore, characterising Europe as left wing on this issue is a mistake.
