My knowledge about the current health care situation in the US mainly comes from television series, so it may not be realistic. Germany is a welfare state, which was first established during the 1880s. I had to look up the stuff, but for the Americans it might be interesting we have used such a system for 130 years - the whole of USA is only 100 years older, and it works quite well. Not perfect, of course.

I just know I have a card of my compulsury health insurance. I don't know any people who don't have. I can't think of a moment in Germany like you sometimes see in American movies/series "Sorry, we can't tread you, you aren't insured". I have no extra private health insurance, because I frankly don't need anyway. Many people have of course, but those cost extra. Your advantages with private insurance are you everything costs more. You get a single room in hospital, you don't have to wait so long (I may comment, yes, if I have a cold, waiting 2 hours to get to the doctor is common, but if you break something and it is serios, you are priority, whether compulsory or private). The hospital spends more money on you, but of course you pay quite a lot of money for that. With compulsory insurance only, I wouldn't get ceramic (plastic?) dental fillings, but amalgam. Or I pay extra for it, of course.
My insurance only covers Germany, so when I went to London last year, I had to make an extra insurance. For 7 Euros for one year. It is still valid today. They would get me a nice coffin and transfer me back to Germany, if I die abroad. Nice for 7 Euros.
Concering other social insurance things: Being unemployed is not so much of a problem. You are assigned a certain room to live (48 qm for a single person, 65 qm for a pair, married). More room if you have kids. Realistically, there is no homeless people in Germany. Of course, there are, but those maybe just don't know whom to ask. A single person will recieve about 350 euros "Hartz IV" (unemployed money) - and the states already pays your rent. For a kid, you get about 140 euros I think - until the kid is 27 years old and/or not living at home anymore.
Anyway, I think it is important that a state is a welfare state and cares about the weaker ones. But it should not go too far. For example, if you have debts here, your TV (up to a certain price!) is considered "lowest standard of living" and can't be taken away. It is just Germany is one of the richest countries in the world and the standard is really high, compared to other countries. I don't like the fact that people in an apprenticeship have mostly less money than a 40 year old unemployed dick who never worked for anything at all.
The USA should def. change something, I guess Obama will look at nations like Germany, Sweden, etc, and will pick out some of the stuff. Not all, of course.
