Tom Geoghegan argues that most Americans would actually be happier under German style social democracy. I tend to agree, as the post below suggests. He makes this case in his new book, Were You Born on the Wrong Continent? and on his blog.
Although, I am not sure if "happier" is the right work--perhaps "fulfilled" would be better. I went hiking with Andreas Weigend not long ago, and we agreed that if it had been raining, it would have been much more fulfilling in a uniquely German sense.
