David Brooks:

…Once there was a bipartisan consensus behind free trade, but that’s not true anymore, either. Even Republicans, by a two-to-one majority, believe free trade is bad for America, according to a Wall Street Journal/NBC poll.

Once upon a time, the fact that hundreds of millions of people around the world are rising out of poverty would have been a source of pride and optimism. But if you listen to the presidential candidates, improvements in the developing world are menacing. Their speeches constitute a symphony of woe about lead-painted toys, manipulated currencies and stolen jobs.

And if Dobbsianism is winning when times are good, you can imagine how attractive it’s going to seem if we enter the serious recession that Larry Summers convincingly and terrifyingly forecasts in yesterday’s Financial Times. If the economy dips as seriously as that, the political climate could shift in ugly ways.

So it’s worth pointing out now more than ever that Dobbsianism is fundamentally wrong. It plays on legitimate anxieties, but it rests at heart on a more existential fear — the fear that America is under assault and is fundamentally fragile. It rests on fears that the America we once knew is bleeding away.

And that’s just not true. In the first place, despite the ups and downs of the business cycle, the United States still possesses the most potent economy on earth. Recently the World Economic Forum and the International Institute for Management Development produced global competitiveness indexes, and once again they both ranked the United States first in the world.

…

William W. Lewis of McKinsey surveyed global competitive in dozens of business sectors a few years ago, and concluded, “The United States is the productivity leader in virtually every industry.”

Second, America’s fundamental economic strength is rooted in the most stable of assets — its values. The U.S. is still an astonishing assimilation machine. It has successfully absorbed more than 20 million legal immigrants over the past quarter-century, an extraordinary influx of human capital. Americans are remarkably fertile. Birthrates are relatively high, meaning that in 2050, the average American will be under 40, while the average European, Chinese and Japanese will be more than a decade older.

The American economy benefits from low levels of corruption. American culture still transmits some ineffable spirit of adventure. American students can’t compete with, say, Singaporean students on standardized tests, but they are innovative and creative throughout their lives. The U.S. standard of living first surpassed the rest of the world’s in about 1740, and despite dozens of cycles of declinist foreboding, the country has resolutely refused to decay.
