Demographics

Current attitudes aren't too kind to the old American way of doing business. In our globalized economy, the most enthusiastically touted approaches are those adopted by centralized, state-dominated economies such as China, Brazil and Russia as well as--somewhat less oppressively--those of the major E.U. states.

Yet the U.S. may well be constructing the best sustainable business model for the 21st Century. It is an approach built on the country's greatest enduring strength--an innovative business culture driven increasingly by a diverse pool of immigrants.

The human world is fast becoming an urban world -- and according to many, the faster that happens and the bigger the cities get, the better off we all will be. The old suburban model, with families enjoying their own space in detached houses, is increasingly behind us; we're heading toward heavier reliance on public transit, greater density, and far less personal space.

Nearly a century and half since the United States last divided, a new "irrepressible conflict" is brewing between the states. It revolves around the expansion of federal power at the expense of state and local prerogatives. It also reflects a growing economic divide, arguably more important than the much discussed ideological one, between very different regional economies.

Time to chuck into the dustbin the cosmopolitan notions so celebrated at global conferences: a world run by wise men of the United Nations, science-driven socialists or their ostensibly more pragmatic twins, global free marketers. We are leaving the age of abstractions and entering one dominated by deep-seated ethnic, religious and cultural loyalties, some with roots from centuries and millennia ago.

Americans, with good reason, increasingly distrust the big, impersonal forces that loom over their lives: Wall Street, federal bureaucracy, Congress and big corporations. But the one thing they still trust is that most basic expression of our mammalian essence: the family.

Class, the Industrial Revolution’s great political dividing line, is enjoying Information Age resurgence. It now threatens the political future of presidents, prime ministers and even Politburo chiefs.

As in the Industrial Age, new technology is displacing whole groups of people — blue- and white-collar workers — as it boosts productivity and creates opportunities for others. Inequality is on the rise — from the developing world to historically egalitarian Scandinavia and Britain.

Over the past half century arguably no place on earth has progressed more than the tiny island state of Singapore. A once impoverished, tropical powder keg packed into 268 square miles at the foot of the Malay Peninsula, the Mandarin-led republic has ascended from its difficult founding in 1965 to one of the richest economies on the planet. Today, in terms of purchasing power, its per capita income stands higher than most European countries' or Japan's and is roughly equal to that of the U.S.

Pundits, planners and urban visionaries—citing everything from changing demographics, soaring energy prices, the rise of the so-called "creative class," and the need to battle global warming—have been predicting for years that America's love affair with the suburbs will soon be over. Their voices have grown louder since the onset of the housing crisis. Suburban neighborhoods, as the Atlantic magazine put it in March 2008, would morph into "the new slums" as people trek back to dense urban spaces.

On a drizzly, warm June night, the bars, galleries, and restaurants along Broadway are packed with young revelers. Traffic moves slowly, as drivers look for parking. The bar at the Donaldson, a boutique hotel, is so packed with stylish patrons that I can’t get a drink. My friend, a local, and I head over to Monte’s, a trendy Italian place down the street. We watch a group of attractive 30-something blondes share a table and gossip. They look like the cast of the latest Housewives series.

Estimates of the United states population at the middle of the 21st century vary, from the U.N.’s 404 million to the U.S. Census Bureau’s 422 to 458 million. To develop a snapshot of the nation at 2050, particularly its astonishing diversity and youthfulness, I use the nice round number of 400 million people, or roughly 100 million more than we have today.
