This structure is already visible in the legions of private contractors in Iraq, as well as in New York's amazingly effective counterterrorist intelligence unit. But as we look out to 2016, the long-term implications are clearer.

Security will become a function of where you live and whom you work for, much as health care is allocated already. Wealthy individuals and multinational corporations will be the first to bail out of our collective system, opting instead to hire private military companies, such as Blackwater and Triple Canopy, to protect their homes and facilities and establish a protective perimeter around daily life. Parallel transportation networks--evolving out of the time-share aircraft companies such as Warren Buffett's NetJets--will cater to this group, leapfrogging its members from one secure, well-appointed lily pad to the next.

Members of the middle class will follow, taking matters into their own hands by forming suburban collectives to share the costs of security--as they do now with education--and shore up delivery of critical services. These "armored suburbs" will deploy and maintain backup generators and communications links; they will be patrolled by civilian police auxiliaries that have received corporate training and boast their own state-of-the-art emergency-response systems. As for those without the means to build their own defense, they will have to make do with the remains of the national system. They will gravitate to America's cities, where they will be subject to ubiquitous surveillance and marginal or nonexistent services. For the poor, there will be no other refuge.
