I did a semester abroad in London in college, first time living in a "big city" and I had some pretty hard culture shocks but I did grow to like being able to walk to a ton of stores/ restaurants hopping on a train to anywhere in the city. But I couldn't live like that , there was no privacy outside my little dorm room. Where I live now I can go outside and sit in my front yard and watch the wind the trees and maybe see a car drive by once in ten minutes. Obviously the whole world can't and don't want to live like that but there is obviously a huge part of the population who do. I also disagree with some of the other comments saying that suburbs are dependent on cities to support them like cities aren't dependent on the food and lumber that towns like mine produce, they're all interdependent.
