Earlier quoted context omitted.
"In other countries with universal healthcare [...]" Not sure where you live or where you've been too, but you make some sweeping arguments about dozens of countries. Mostly everything you say is wrong about Germany (>65% taxation, no private insurance, share room with 5 people, treatments in your room, toilet not in the room, uneatable food, ...).
Germany is one of the five countries, and it has the lowest taxes among them. The rest are Austria and Scandinavian countries where total taxation rate approaches 70% all things factored in (I'm counting indirect taxes as well). Isn't it interesting that the best healthcare system in the world is entirely privatized, in Switzerland?
Both have amazing public/private systems, where everyone has access to public healthcare, and if you want to pay the extra money, you can go private. They also have (very affordable and fair) health insurance if you want that extra security.
The public hospitals are fine in both countries, you'll get the critical care you need, when you need it. There aren't people dying of cancer because the government can't afford treatment. Sure, it's a bit slow for non-essential and elective treatment (e.g. a hip replacement or other corrective surgery), but it does get done eventually and as I said you can always go private, which is a lot cheaper than the USA, as they have to compete with free healthcare.
I'm really not sure why you keep quoting total taxation as some kind of negative point regarding countries with universal healthcare and functioning social welfare systems? Quality of life, both for individuals and for the whole population is a much more important measure.
