According to the History of Man in the 2010s, the following will happen in the united states:

Amid a vast wasteland of abandoned factories and burning cities falling into total anarchy, the government of the United States willingly hands its responsibilities over to the military, which swiftly installs a new Constitution enshrining the sanctity of land owner rights. The elite of this New Perfect America shelters itself in fortified, self-sufficient city-states, regulated by a council of military and religious elders. Much of the nation's infrastructure collapses. The cities are left to rot, as libertarian cadres, anarcho-syndicalists, survivalists, armed religious cults and race-identity supremists fight over the table scraps.
