I'm going with Rumsfeld, Cheney, et-al from their PNAC document on this one.  That is, the most likely end-game is a one-world government.  In that case I would expect the management strategies promulgated by the leadership to be in many ways almost indistinguishable from those employed by the Soviets and other totalitarian regimes, and I would hold near zero hope for anything resembling 'democracy' (though it may well be called that.)  The methods of control used would include austerity, surveillance, anonymous informants, etc.  Basically any structure which keeps individuals separate and suspicious of one another.
