Suburgatory is a TV show about a teen girl and her family who move from inner city Manhattan to a outer-suburb (unnamed).
The suburban people are shown as incredibly affluent. Lots of expensive fashion and plastic surgery.
I get the impression from the show that in the US, the most wealthy people live not in the inner city, but out in the suburbs. I'm not sure it this is correct. Is it a fictional component of the show? Is it a exaggeration?
Where I am from, Perth western Australia this is not true at all: (most of) the inner suburbs/CBD are incredibly pricy and (most of) the outer suburbs have a fairly poor reputation (Mostly jokes about the prevalence of alcholism, and/or stabbings). Perth does however have things like the "Hollow City" phenomenon.
