In Brave New World, what is the role of the country in the World State economy?

The country in literature, typically represents calm and
quiet reflection and an image of beauty and serenity.  This is not so in Brave New
World.  In this novel, the country exists to aid the
economy.

The World State's economy thrives on consumption
of goods and services which then require the increased production of those goods and
services.  In a nutshell, nobody recycles in this society, as that does not leading to
production:  such the phrase, "Ending is Better than
Mending!" 

The country serves to provide for this economy. 
First, individuals must consume transportation to get there, such as flying in a
helicopter.  These helicopters require maintenance.   In addtion, several "high-tech"
sporting events take place in the country.  Centrifugal Bumblepuppy and Escalator Golf
are two such pasttimes that require quite a bit of labor, upkeep and equipment.  All of
this helps the economy of the World State.
