Wow, so much spewed opinion you seem to think is fact.
First, air in cities is generally worse than outside cities. You'll be able to find counter-examples, say outside a rural factory, but generally, no matter where you go in the world, city air is worse than rural air.
You're right that we are mostly a social species. However, this means different things to different people. Maybe you are more social than most. Personally, I have a family I enjoy seeing, and other than that I'm quite happy interacting with just a few other people every week. I neither want nor need more. The difference between the two of us seems to be that I'm willing to let you lead your lifestyle whereas you're unwilling to let me lead mine.
You're right that cities are easier on the environment on a per capita basis. Of course, there are also plenty of ways that people could be more distributed in a more environmentally advantageous fashion. If you have any interest in the subject and a certain level of intelligence it wouldn't be hard for you to come up with some ideas. Travelling around in other first world countries in Europe would also give you plenty of other viewpoints.
Additionally, while it's true that cities do in some ways subsidize rural areas, where do you think your food comes from? Other cities? Around here, stickers reminding us that "farmers feed cities" are quite common. Thank you for reminding me that there are people out there like you who need reminding. Finally, it's very rare for roads/phoneline/internet/etc to lead "nowhere". They lead somewhere, just apparently to areas you don't think are necessary.
Since you're the one painting "small town America" with one wide brush that includes racists, idiots, homophobes and chain store hellscapes, I'll throw that one back to you and state you're the one with the perception problems. The world outside your city is much bigger, and more important, than you seem to make it out to be. There are plenty racists, idiots, homophobes and chain stores in urban environments, and plenty of intelligent, tolerant, and educated people working in small business in small towns and rural communities all across your country.
For the record, I've spent close to a decade living in the US. I've lived in some of the world's largest cities, and worked in and travelled to many more. I feel very fortunate and privileged to now live on a farm in the country. Overall, my quality of life here is better than anywhere else I've lived.
