As I said before (I believe it was to Anticlimactic): American talking point of "socialism" doesn't really exist, since Americans are mixing two ideologies. One is Socio-democracy and the other is Socialism/Communism. Even the dumbass Bernie can't really get this straight and that will cost him BIG.
Communism/socialism is basically everything you have ever heard about the USSR, Mao, Cuba, the gulags, the hunger ... etc. While soco-democracy is developed capitalism that has stockmarket, free and fair elections every few years, the taxes are somewhat higher than in classic capitalism but healthcare sector is much more friendly to people. Both in costs and bureaucracy, plus going to university is tuition free or much cheaper. Plus legal and physical safety is higher than in "every man for himself" societies. All of this depends from country to country since there is a fair amount of diversity in the details but all mentioned points are the general picture. While on the other hand my country had the whole war of independence so that it can shift from Communism to socio-democracy. Here people are actually cursing when "globalists" are pushing at us "classic Capitalism" as replacement/alternative for socio-democracy. Therefore for me these are really two different things.
Wait times are easy. If there is a emergency you are going over the line, period. Or if they are really having waiting lists they often tell you where around the city you have shorter waiting lists for what you need, since you aren't bound to a single specialist. However from what I have heard USA also has problems with waiting so it isn't that this is back an white issue, especially if you are poor. Plus as the government is involved you can nudge this through democracy, writing to officials or even through snap elections if needed. Therefore even if all parties want to crash the healthcare system you can always just invent new party and bypass the whole system, if there is really a dire need for that. I mean the greatest benefit is probably in the stress, because in the case your life went completely to hell you can always get medical treatment. The same goes for your sick kids and scenarios that something happens to you. Plus Ambulance has no out of pocket costs.
When I go to the doctor I am always received right away and only if I need a specialist I will need to wait for some time (but if it is emergency I am going over the line).
I just come in and I say what is wrong, and therefore I either get a prescription or they send me to a specialist for further tests or whatever. There is no paperwork involved for me. I have even gotten surgery without any out of pocket paying, while the most expensive prescription drug I have ever bought wasn't more than 20$ (most of them are around 5-10$, if they are are not free at spot) Plus outside of socialized medicine there are a few private clinics for those that "insert the reason", but those are costly. There is room for further improvement and we aren't the most advanced socio-democracy out there, but next to what I see in USA this is really great system for average working people. Especially since here there are no healthcare related bankruptcies.
