Raquel: After the Heathen Wars of 2006, the US is split into Heathen Pockets (the Northeast Corridor and West Coast) and Fundy Pockets (everything else). The Heathens begin construction of Low-Orbit geosychroneous stations, planning to Get the Hell Out of Dodge, but this takes time. Meanwhile, Fundies in the center of the former US find themselves living in an economic dustbowl, and crops begin rotting in the fields. No longer believing in evolution, family planning, or a spherical earth, they quickly begin to overpopulate and yet are scared to leave the new dustbowl (termed "Damnation Alley" by the Heathens) because they might fall off the edge of the earth, or be forced into sodomy with non-whites. Eventually the middle states decline into human sacrifice, with daily blood offerings to Jehovah.
The Heathen Zones fare little better. Refugees of Heathens from the Fundy Zone stream in daily, overloading the cities and fighting for scarce resources. "Will Sell iPod for Food" signs are seen on every corner. The southern tip of Florida declares its indepedence from the concept of "nation" and incorporates as the first Constitutional MegaCorp. Seattle looks ready to follow suit. Government is abandoned in favor of "Lodge Meetings," but these have no ability to enforce the few decisions made at them. Corporate arcologies begin appearing, their Employee Handbooks taking the place of the American Consitution. The Heathens are split between the liberal activists, who continue to oppose the corporations' environmental policies but live in near anarchy, eating nutri-paste; and the Engineers, who are mainly people of color with educations, trying to provide for their families in the coffin-size rooms of arcologies.
Oddly, Top 40 music, network sitcoms, and fashion magazines are still regularly available.
