When Americans think of our nation's power (or our imminent lack of it) we tend to point to the national debts, GDP or military prowess. Few have focused on what may well be the country's most historically significant and powerful weapon: its emergence as the modern world's first multiracial superpower.

Gentry liberalism, so hot just a year ago, is now in full retreat, a victim of its hypocrisy and fundamental contradictions. Its collapse threatens the coherence of President Barack Obama's message as he prepares for his State of the Union speech on Wednesday.

Now that Phoenix's ascendancy has been at least momentarily suspended, its residents are no doubt wondering what comes next. One tendency is to say the city needs to grow up and become more like East Coast cities or Portland, Ore., with dense urban cores and well-developed rail transit. The other ready option is always inertia - a tendency to wait for things to come back the way they were.

Neither approach will work in the long run.

America's population growth makes it a notable outlier among the advanced industrialized countries. The country boasts a fertility rate 50% higher than that of Russia, Germany or Japan and well above that of China, Italy, Singapore, North Korea and virtually all of eastern Europe. Add to that the even greater impact of continued large-scale immigration to America from around the world. By the year 2050, the U.S. population will swell by roughly 100 million, and the country's demographic vitality will drive its economic resilience in the coming decades.

A year into the Obama administration, America’s dominant geography, suburbia, is now in open revolt against an urban-centric regime that many perceive threatens their way of life, values, and economic future. Scott Brown’s huge upset victory by 5 percent in Massachusetts, which supported Obama by 26 percentage points in 2008, largely was propelled by a wave of support from middle-income suburbs all around Boston. The contrast with 2008 could not be plainer.

In this high-tech information age few look to the most basic industries as sources of national economic power. Yet no sector in America is better positioned for the future than agriculture--if we allow it to reach its potential.

Like manufacturers and homebuilders before them, farmers have found themselves in the crosshairs of urban aesthetes and green activists who hope to impose their own Utopian vision of agriculture. This vision includes shutting down large-scale scientifically run farms and replacing them with small organic homesteads and urban gardens.

By all historical logic and tradition, Wall Street’s outrageous bonuses—almost $20 billion to Goldman Sachs alone—should be setting a populist wildfire across the precincts of the Democratic Party. Yet right now, the Democrats in both the White House and Congress seem content to confront such outrageous fortune with little more than hearings and mild legislative remedies—like a proposed new bank tax, which, over the next decade, seeks to collect $90 to $100 billion. This amounts, on an annual basis, to about half of this year’s bonus for Goldman’s gold diggers alone.

The opening last week of the world's tallest building, the half-mile-high Burj Dubai, has largely been greeted with guffaws and groans. The Daily Telegraph labeled it "the new pinnacle of vanity"--"a purposeless monument to the subprime era." The Wall Street Journal compared it to the Tower of Babel. (When the Empire State Building was completed in 1931, in the throes of the greatest financial crisis of the 20th century, it was met with similar jeers. The then-tallest building in the world was called the Empty State Building, and it remained vacant for several years.)

Yet the Burj's completion--indeed the whole wild enterprise known as Dubai--could signal a potential opportunity to the global community: turning the place into the headquarters for that other misguided ship, the United Nations.

Reversing the general course of history, economics or demography is never easy, despite even the most dogged efforts of the best-connected political operatives working today.

Since the 2006 elections--and even more so after 2008--blue-state politicians have enjoyed a monopoly of power unprecedented in recent history. Hardcore blue staters control virtually every major Congressional committee, as well as the House Speakership and the White House. Yet they still have proved incapable of reversing the demographic and economic decline in the nation's most "progressive" cities and states.

When Michael Bloomberg stood on the steps of City Hall last week to be sworn in for a third term as New York City's mayor, he spoke in upbeat terms about the challenges ahead. The situation, however, is far more difficult than he portrays it. American financial power has shifted from New York to Washington, while global clout moves toward Singapore, Hong Kong, and Shanghai. Even if the local economy rebounds, the traditional media industries that employ many of Bloomberg's influential constituents likely will continue to decline.
