from my experiences living in the US vs. germany i am tempted to state the following thesis:
if you are part of the top 15 % (income, intelligence, education...), living in the US is probably better than living in germany. you have lower taxes and you can afford a superior lifestile.
if you are a part of the rest (or even the lower 15%), germany would be a better place to live. in germany, the rich are forced to subsidise a better lifestile of the rest of society. you dont have to worry about health insurance (and from my personal experience, i can tell you that the german socialised medicine is in an extremely good shape compared to average american services), you dont have to work that much, i actually think you have more freedom just because of that.
