Haha, saying that Germany is communist is actually a good proof of ignorance. In fact, I believe (but I may be wrong) that not a single country in Western Europe is communist. In France, which seems to be thought as a communist country by quite a few people in the United States, the communist political party is almost inexistant and gathers something like 2% of the suffrage.
As for the debate about the best country... I doubt there is a best country. As long as you have a good situation in a developped country, or in a country which heavily favour the rich, you are likely to meet the best conditions anyway. However, if you don't have a good social or financial situation, it may be interesting to see how your country can provide you and access to good life conditions by lowering inequalities. That's a point where the United States are not so good (at least, from my point of view).
This kind of thing can be seen with various studies and indexes, like the following ones :
HUman Developement Index,
Human Poverty Index,
Democracy Index,
Corruption Index or
Education Index.
Those are of course only statistics, and summarizing the situation of a whole country by a single number doesn't mean that much, but still, that's relevant.
As for not going out of the United States because you don't see the need of discovering other cultures… it just mean you're not curious and that's quite sad (more than having false conceptions about other countries), especially considering that the US still lack a great historical and cultural background because of it's "recent" birth, despite its current influence over the world.
Edit : Chair, don't even ask me how I happened to post here XD
