East Jerzi is a lot like a very homogenized and compact United States, as far as culture and architecture goes. There's nothing that really sets itself apart from the rest of the world as it's mostly a concrete jungle besides the untouched forests that remain. A lot of the people that live there find it to be "fine" or wish to aspire to live elsewhere or seek out a more fulfilling life.

As far as a West Jerzi, there IS one! It's an island country to the west (of course) that is bridged to the mainland East Jerzi, and is home to mostly rich and affluent people. There's absolutely a culture of looking down on middle class or poorer people, and a lot of the people that try to live there are those that see themselves as "temporarily embarrassed millionaires" and want to live that rich life.
