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.
• Employee rights
• Health insurance
• Militarism ("What is an appropriate amount to spend on military")
• Global Warming
For example in my country our right wing government had made good on a right wing promise to increase the maximum highway speed from 120kph to 130kph.
Some years later however it turned out that the presence of highways contributed to dangerous levels of nitric oxides (edited from nitrogen) in the air and a judge forced that same administration to reduce the maximum speed from 130kph to 100kph.
Now legislation (and reality) has changed a right wing position from being "disregard the environment, prioritise economy and increase the speed" to "disregard health, prioritise economy and increase the speed". The same position was basically transformed into a more extreme position due to the circumstances changing.
I imagine that same thing holds for many topics. It sure feels a lot more extreme to advocate gun regulation when doing so in opposition of school shooting victims. I generally support the idea of gun ownership, but the shootings definitely forced me to have a more nuanced opinion that shifted my position from the conservative side to the progressive side.
