I don’t have a lot to add to Ryan’s take on Europe vs. America. However, I will say the tastes which determine whether or not you like Europe is whether or not you like people – lots of people.
European middle class life seem to be set up in ways that maximize your contact with other people. From cafes to public transportation to the economic reversal of suburbs and the urban core the society expects that you will be okay with being intermingling.
To a large extent I think ethnic anxiety is what keeps Americans from feeling as comfortable in those situations. However, a less other people focused America is more appealing to introverts. The US is in many ways a dork paradise.
