Just to note, it’s not free, it’s not magic, it’s just better regulated. I’ve lived in a few countries with socialized healthcare, and we still pay insurance. It’s just a lot less since we don’t have to cover ever-increasing insurance profits, and there is no such thing as “out of network” as long as you don’t leave the country (and the rest of the EU).
My premium is 116 EUR for full coverage per month, with no maximum coverage or any other fees, and every healthcare institution in the EU is going to treat me for that in an emergency, for no additional charge. If I need extended treatment, I will get transported to the institution that’s most convenient for me (and thus, the system), and be treated there. Dental, mental healthcare included.
I still pay for some OTC medicine, but prices are kept low.
